Abstract
Injection of recombinant tissue plasminogen activator (rt-PA) is the standard drug treatment for thrombolysis. However, rt-PA shows risk of hemorrhages and limited efficiency even at high doses. Polysaccharide-poly(isobutylcyanoacrylate) nanoparticles functionalized with fucoidan and loaded with rt-PA were designed to accumulate on the thrombus. Fucoidan has a nanomolar affinity for the P-selectin expressed by activated platelets in the thrombus. Solid spherical fluorescent nanoparticles with a hydrodynamic diameter of 136 ± 4 nm were synthesized by redox radical emulsion polymerization. The clinical rt-PA formulation was successfully loaded by adsorption on aminated nanoparticles and able to be released in vitro. We validated the in vitro fibrinolytic activity and binding under flow to both recombinant P-selectin and activated platelet aggregates. The thrombolysis efficiency was demonstrated in a mouse model of venous thrombosis by monitoring the platelet density with intravital microscopy. This study supports the hypothesis that fucoidan-nanoparticles improve the rt-PA efficiency. This work establishes the proof-of-concept of fucoidan-based carriers for targeted thrombolysis.

Abstract
Effective dye decolorization in wastewater still shows a big challenge. Although the biological methods, especially using enzymes, offer alternative and effective process for dye degradation and overcome the limitations of chemical and physical methods such as the instability, lack of reusability and high cost of free enzymes strictly, which limit their use in many scientific and technical applications. Enzymes rapidly lose their activities in aqueous solutions and against environmental changes due to their very susceptibility and unfavorable conformations. Herein, we report preparation of the enzyme-inorganic hybrid nanostructures with flower-like shape consisting of Turkish black radish peroxidase and Cu2+ metal ions using an encouraging enzyme immobilization approach. The peroxidase-Cu2+ hybrid nanoflowers (NFs) exhibited enhanced stability and activity towards various pH values and provided excellent dye decolorization efficiency for Victoria blue (VB) dye with more than 90% within 1 h. The NFs were also repeatedly used in efficient and caused 77% VB decolorization efficiency even at tenth cycles. However, to the best of our knowledge, for the first time, we prepared peroxidase enzyme isolated from Turkish black radish incorporated NFs and used them for dye decolorization. We believe that the NFs can be promising materials for dye decolorization in real wastewater treatment.

Abstract
The role of nanoparticle interaction with biomolecules to form a biocorona is the key to nanoparticle behavior and its consequences in the physiological environment. Since the adsorbed biocorona decides the fate of a nanomaterials in vivo, and thus a comprehensive understanding of the dynamic interactions of the proteins with the nanoparticle is imperative. Herein we investigate the interaction of a model protein, lysozyme with silver nanoparticles (AgNPs) using fluorescence, synchronous fluorescence, UV-vis absorption spectrum and circular dichroism (CD) techniques under the physiological conditions. The results indicated that the binding of AgNPs to lysozyme may be a static quenching mechanism. With the analysis of the fluorescence spectral data, the binding constants and the thermodynamic parameters were determined, which suggests that the binding of AgNPs to lysozyme is a spontaneous process. Moreover, it was demonstrated that the main acting forces between AgNPs and lysozyme may be hydrophobic interactions. At the same time, the conformational change of lysozyme induced by AgNPs was investigated with synchronous fluorescence spectroscopy and CD techniques. The results of kinetic studies reveal that the adsorption of lysozyme on AgNPs surface tends to follow pseudo-second-order kinetic characteristic with obvious hysteresis effect.

Abstract
Molecular imaging has emerged as an indispensable technology in the development and application of drug delivery systems. Targeted imaging agents report the presence of biomolecules, including therapeutic targets and disease biomarkers, while the biological behaviour of labelled delivery systems can be non-invasively assessed in real time. As an imaging modality, fluorescence offers additional signal specificity and dynamic information due to the inherent responsivity of fluorescence agents to interactions with other optical species and with their environment. Harnessing this responsivity is the basis of activatable fluorescence imaging, where interactions between an engineered fluorescence agent and its biological target induce a fluorogenic response. Small molecule activatable agents are frequently derivatives of common fluorophores designed to chemically react with their target. Macromolecular scale agents are useful for imaging proteins and nucleic acids, although their biological delivery can be difficult. Nanoscale activatable agents combine the responsivity of fluorophores with the unique optical and physical properties of nanomaterials. The molecular imaging application and overall complexity of biological target dictate the most advantageous fluorescence agent size scale and activation strategy.

Abstract
Nonspecific assays utilizing time-resolved luminescence resonance energy transfer (TR-LRET) are developed for two applications: to monitor protein adsorption efficiency and to assess the degree of surface coverage on the solid phase. We successfully measure the adsorption efficiency of non-sedimenting nanoparticles since this has been notoriously difficult to determine. Monitoring of the protein adsorption on nanoparticles does not require the nanoparticles with the adsorbed protein to be washed and it is based on the competitive adsorption between the non-adsorbed analyte protein and the acceptor-labeled protein to donor europium(iii) polystyrene nanoparticles. The application for assessing the degree of surface coverage is performed with the final coated and washed analyte nanoparticles and it requires no fluorescent labeling of the studied protein. This application utilizes the competitive adsorption of the acceptor-labeled protein on analyte nanoparticles partly covered with protein and donor europium(iii) polystyrene nanoparticles. The developed methods detect either non-adsorbed protein or uncovered nanoparticle surface, not the proteins adsorbed on the nanoparticles. This is not achievable with the traditional total protein quantification assays applied for monitoring protein adsorption since both non-adsorbed and adsorbed protein are detected and their separation is required. Thus, the developed application for monitoring protein adsorption is user-friendly, requires no centrifugal instrumentation, and is applicable also for small nanoparticles requiring ultracentrifugation. No special expertise or investment in costly instruments is required compared to the existing methods, such as spectroscopic techniques, isothermal titration calorimetry, and surface plasmon resonance. The application for assessing the degree of surface coverage is compared to a reference literature method that comprised the analysis of adsorbed fluorescently labeled protein. The saturation reached at similar protein concentrations showing the reliability of the assay. Our results suggest that the developed applications could be exploited as rapid tools for protein adsorption studies on nanoparticles and for quality control and characterization of the coating processes.

Abstract
Quantitative analysis of the interactions between nanomaterials and their surrounding environment is crucial for safety evaluation in the application of nanotechnology as well as its development and standardization. In this chapter, we demonstrate the importance of the adsorption of surrounding molecules onto the surface of nanomaterials by forming biocorona and thus impact the bio-identity and fate of those materials. We illustrate the key factors including various physical forces in determining the interaction happening at bio-nano interfaces. We further discuss the mathematical endeavors in explaining and predicting the adsorption phenomena, and propose a new statistics-based surface adsorption model, the Biological Surface Adsorption Index (BSAI), to quantitatively analyze the interaction profile of surface adsorption of a large group of small organic molecules onto nanomaterials with varying surface physicochemical properties, first employing five descriptors representing the surface energy profile of the nanomaterials, then further incorporating traditional semi-empirical adsorption models to address concentration effects of solutes. These Advancements in surface adsorption modelling showed a promising development in the application of quantitative predictive models in biological applications, nanomedicine, and environmental safety assessment of nanomaterials.

Abstract
Nisin is a well-recognised antimicrobial peptide (AMP) used in food industry. However, efficacy of the peptide has been compromised due to development of resistance in different bacterial strains. Here, efficacy of the peptide upon assembly at a silver nanoparticle (AgNP) interface has been characterized. To this end, experimental and simulation studies are done to characterize the interfacial assembly of nisin and underlie antibacterial mechanism. Being an AMP, efficacy of an intact nisin is explored against Gram-positive and Gram-negative bacteria, and compared with antibacterial propensity of the interfacially assembled nisin. Antibacterial propensity, upon the assembly, increases against both kinds of bacteria. Interestingly, the growth inhibition studies of the interfacially assembled nisin indicate that the originally nisin resistant Gram-negative bacteria become sensitive to the nanomolar nisin concentrations. Furthermore, reactive oxygen species (ROS) measurements together with confocal microscopy imaging indicate that the increase in interfacial and intracellular ROS production upon the treatment is underling mechanism of enhanced antibacterial propensity of the assembled nisin. Thus, the study observed that the interfacial assembly of nisin at AgNP interface enhances the efficacy of nisin against different spectrum of bacteria, where the intact nisin is largely ineffective for the studied concentrations.

Abstract
Functionalized superparamagnetic iron oxide nanoparticles are frequently used to develop vehicles for drug delivery, hyperthermia, and photodynamic therapy and as tools used for magnetic separation and purification of proteins or for biomolecular imaging. Depending on the application, there are various possible covalent and non-covalent approaches for the functionalization of particles, each of them shows different advantages and disadvantages for drug release and activity at the desired location.Particularly important for the production of adsorptive and covalent bound drugs to nanoparticles is the pureness of the involved formulation. Especially the covalent binding strategy demands defined chemistry of the drug, which is stabilized by excess free amino acids which could reduce reaction efficiency. In this study, we therefore used tangential flow filtration (TFF) method to purify the drugs before the reaction and used the frequently applied and clinically available recombinant tissue plasminogen activator (tPA; Actilyse(®)) as a proof of concept. We then coupled the tPA preparation to polyacrylic acid-co-maleic acid (PAM)-coated superparamagnetic iron oxide nanoparticles (SPIONs) using an amino-reactive activated ester reaction and compared these particles to PAM-coated SPIONs with electrostatically adsorbed tPA.Using dynamic light scattering (DLS) and pH-dependent electrokinetic mobility measurements, we showed that surface properties of the SPIONs were significantly greater affected after activation of the particles compared to the adsorption controls. Different in vitro assays were used to investigate the activity of tPA after coupling to the particles and purification of the ferrofluid. Covalent linkage significantly improves the reactivity and long-term stability of the conjugated SPION-tPA system compared to simple adsorption. In conclusion, we have shown an effective way to produce SPIONs with covalent and non-covalent ultra-filtrated drugs. We showed that using activated ester reaction, immobilization of the protein was significantly better than in adsorptive approaches. Investigation of those functionalized SPIONs revealed diverging attributes, which should be taken into account when developing nanoparticles for different applications.

Abstract
A co-engineered nanoparticle/protein peroxide detector is created. This system features a gold nanoparticle functionalized with a galactose headgroup (AuNP-Gal) that reacts covalently with a boronate-modified green fluorescent protein (PB-GFP). Boronate acid-saccharide complexation between PB-GFP and AuNP-Gal affords a highly stable assembly. This complex is disrupted by peroxide, allowing quantitative and selective monitoring of hydrogen peroxide production in real time.

Fibrin(ogen)olytic and antiplatelet activities of a subtilisin-like protease from Solanum tuberosum (StSBTc-3). Biochimie 2016; 125:163-70.

Abstract
Plant serine proteases have been widely used in food science and technology as well as in medicine. In this sense, several plant serine proteases have been proposed as potential anti-coagulants and anti-platelet agents. Previously, we have reported the purification and identification of a plant serine protease from Solanum tuberosum leaves. This potato enzyme, named as StSBTc-3, has a molecular weight of 72 kDa and it was characterized as a subtilisin like protease. In this work we determine and characterize the biochemical and medicinal properties of StSBTc-3. Results obtained show that, like the reported to other plant serine proteases, StSBTc-3 is able to degrade all chains of human fibrinogen and to produces fibrin clot lysis in a dose dependent manner. The enzyme efficiently hydrolyzes β subunit followed by partially hydrolyzed α and γ subunits of human fibrinogen. Assays performed to determine StSBTc-3 substrate specificity using oxidized insulin β-chain as substrate, show seven cleavage sites: Asn3-Gln4; Cys7-Gly8; Glu13-Ala14; Leu15-Tyr16; Tyr16-Leu17; Arg22-Gly23 and Phe25-Tyr26, all of them were previously reported for other serine proteases with fibrinogenolytic activity. The maximum StSBTc-3 fibrinogenolytic activity was determined at pH 8.0 and at 37 C. Additionally, we demonstrate that StSBTc-3 is able to inhibit platelet aggregation and is unable to exert cytotoxic activity on human erythrocytes in vitro at all concentrations assayed. These results suggest that StSBTc-3 could be evaluated as a new agent to be used in the treatment of thromboembolic disorders such as strokes, pulmonary embolism and deep vein thrombosis.

Abstract
ABSTRACT Quantum dots (QDs) are fluorescence nanoparticles (NPs) with unique optic properties which allow their use as probes in chemical, biological, immunological, and molecular imaging. QDs linked with target ligands such as peptides or small molecules can be used as tumor biomarkers. These particles are a promising tool for selective, fast, and sensitive tagging and imaging in medicine. In this study, an attempt was made to use QDs as a marker for human metallothionein (MT) isoforms 1 and 2. Four kinds of CdTe QDs of different sizes bioconjugated with MT were analyzed using the chip-CE technique. Based on the results, it can be concluded that MT is willing to interact with QDs, and the chip-CE technique enables the observation of their complexes. It was also observed that changes ranging roughly 6-7 kDa, a value corresponding to the MT monomer, depend on the hydrodynamic diameters of QDs; also, the MT sample without cadmium interacted stronger with QDs than MT saturated with cadmium. Results show that MT is willing to interact with smaller QDs (blue CdTe) rather than larger ones QDs (red CdTe). To our knowledge, chip-CE has not previously been applied in the study of CdTe QDs interaction with MT. GRAPHICAL ABSTRACT

Abstract
A study on the adsorption of proteins from fetal bovine serum (FBS) on spherical dense and mesoporous silica nanoparticles with a wide range of diameters, from 70 to 900 nm, is presented. Monodisperse populations of particles with a range of diameters were obtained through modifications of the Stöber method. Extensive characterization of the particles was then performed using N2 physisorption, TEM, DLS, and ζ-potential. Following serum exposure, proteomic evaluation in concert with thermogravimetric analysis revealed the associated concentrations of each protein identified in the hard corona. Small particles adsorbed the largest amount of protein, due to their larger external surface area. Proteins with low molecular weights (<50 kDa) constituted the majority of the protein corona, totaling between 60 and 80% of the total mass of adsorbed protein. Here, the higher surface curvature of small particles favors the enrichment of smaller proteins. Porosity does not promote protein adsorption but improves deposition of the low molecular weight protein fraction due to the size-exclusion effect related to pore diameter. These results have important implications for the use of dense and porous silica nanoparticles in biomedical applications.

Abstract
Spectrometrically or optically encoded microsphere based suspension array technology (SAT) is applicable to the high-throughput, simultaneous detection of multiple analytes within a small, single sample volume. Thanks to the rapid development of nanotechnology, tremendous progress has been made in the multiplexed detecting capability, sensitivity, and photostability of suspension arrays. In this review, we first focus on the current stock of nanoparticle-based barcodes as well as the manufacturing technologies required for their production. We then move on to discuss all existing barcode-based bioanalysis patterns, including the various labels used in suspension arrays, label-free platforms, signal amplification methods, and fluorescence resonance energy transfer (FRET)-based platforms. We then introduce automatic platforms for suspension arrays that use superparamagnetic nanoparticle-based microspheres. Finally, we summarize the current challenges and their proposed solutions, which are centered on improving encoding capacities, alternative probe possibilities, nonspecificity suppression, directional immobilization, and "point of care" platforms. Throughout this review, we aim to provide a comprehensive guide for the design of suspension arrays, with the goal of improving their performance in areas such as multiplexing capacity, throughput, sensitivity, and cost effectiveness. We hope that our summary on the state-of-the-art development of these arrays, our commentary on future challenges, and some proposed avenues for further advances will help drive the development of suspension array technology and its related fields.

Abstract
Considerable efforts have been made to synthesize and characterize protein-nanoparticle conjugates (protein-NPs) for their promising applications in bionanotechnology. However, protein concentration determination in the protein-NPs has so far not been reported. In this Letter, we present a simple and nondestructive approach to quantify the protein concentration in the protein-NPs aqueous solution using circular dichroism (CD) spectroscopy. Carbon dots (∼4 nm), gold nanoparticles (∼10 nm), and polyethylene glycol (PEG, molecular weight ∼3000) were either physically mixed or covalently conjugated (not in the case of gold nanoparticles) with proteins (human transferrin, human serum albumin, and ovalbumin). We were able to quantify the protein concentration in the protein-nanoparticle conjugates using a calibration curve from the CD spectra.

Abstract
Nanoparticle-cored dendrimers (NCDs) are now offering themselves as versatile carriers because of their colloidal stability, tunable membrane properties and ability to encapsulate or integrate a broad range of drugs and molecules. This kind of hybrid nanocomposite aims to combine the advantages of stimuli-responsive dendritic coatings, in order to regulate the drug release behaviour under different conditions and improve the biocompatibility and in vivo half-time circulation of the inorganic nanoparticles. Size, surface chemistry and shape are key nanocarrier properties to evaluate. Here, we have reviewed the most recent advances of NCDs in drug delivery systems, compared their behaviour with non-dendritic stabilized nanoparticles and highlighted their challenges and promising applications in the future.

Abstract
![]()
While
a host of methods exist to deliver genetic materials or small
molecules to cells, very few are available for protein delivery to
the cytosol. We describe a modular, light-activated nanocarrier that
transports proteins into cells by receptor-mediated endocytosis and
delivers the cargo to the cytosol by light triggered endosomal escape.
The platform is based on hollow gold nanoshells (HGN) with polyhistidine
tagged proteins attached through an avidity-enhanced, nickel chelation
linking layer; here, we used green fluorescent protein (GFP) as a
model deliverable cargo. Endosomal uptake of the GFP loaded nanocarrier
was mediated by a C-end Rule (CendR) internalizing peptide fused to
the GFP. Focused femtosecond pulsed-laser excitation triggered protein
release from the nanocarrier and endosome disruption, and the released
protein was capable of targeting the nucleoli, a model intracellular
organelle. We further demonstrate the generality of the approach by
loading and releasing Sox2 and p53. This method for targeting of individual
cells, with resolution similar to microinjection, provides spatial
and temporal control over protein delivery.

Abstract
While there are a number of methods for attaching gold nanoparticles (AuNPs) to biomolecules, the existing strategies suffer from nonspecific AuNP adsorption, reagents that are unstable in aqueous solutions, and/or long reaction times. To improve upon existing AuNP bioconjugation strategies, we have adapted a recently reported potassium ferricyanide-mediated oxidative coupling reaction for the attachment of aniline-functionalized AuNPs to o-aminophenol-containing oligonucleotides, peptides, and proteins. The aniline-AuNPs are stable in aqueous solutions, show little-to-no nonspecific adsorption with biomolecules, and react rapidly (30 min) with o-aminophenols under mild conditions (pH 6.5, 1 mM oxidant).

Abstract
PURPOSE Mucopolysaccharidosis I is a genetic disorder caused by alpha-L-iduronidase deficiency. Its primary treatment is enzyme replacement therapy (ERT), which has limitations such as a high cost and a need for repeated infusions over the patient's lifetime. Considering that nanotechnological approaches may enhance enzyme delivery to organs and can reduce the dosage thereby enhancing ERT efficiency and/or reducing its cost, we synthesized laronidase surface-functionalized lipid-core nanocapsules (L-MLNC). METHODS L-MLNCs were synthesized by using a metal complex. Size distributions were evaluated by laser diffraction and dynamic light scattering. The kinetic properties, cytotoxicity, cell uptake mechanisms, clearance profile and biodistribution were evaluated. RESULTS Size distributions showed a D[4,3] of 134 nm and a z-average diameter of 71 nm. L-MLNC enhanced the Vmax and Kcat in comparison with laronidase. L-MLNC is not cytotoxic, and nanocapsule uptake by active transport is not only mediated by mannose-6-phosphate receptors. The clearance profile is better for L-MLNC than for laronidase. A biodistribution analysis showed enhanced enzyme activity in different organs within 4 h and 24 h for L-MLNC. CONCLUSIONS The use of lipid-core nanocapsules as building blocks to synthesize surface-functionalized nanocapsules represents a new platform for producing decorated soft nanoparticles that are able to modify drug biodistribution.

Abstract
Nanomanipulation of matter to create responsive, ordered materials still remains extremely challenging. Supramolecular chemistry has inspired new strategies by which such nanomaterials can be synthesized step by step by exploiting the self-recognition properties of molecules. In this work, the ring-shaped architecture of the 2-Cys peroxiredoxin I protein from Schistosoma mansoni, engineered to have metal ion-binding sites, is used as a template to build up 1D nanoscopic structures through metal-induced self-assembly. Chromatographic and microscopic analyses demonstrate the ability of the protein rings to stack directionally upon interaction with divalent metal ions and form well-defined nanotubes by exploiting the intrinsic recognition properties of the ring surfaces. Taking advantage of such behavior, the rings are then used to capture colloidal Ni(2+)-functionalized ultrasmall gold nanoparticles and arrange them into 1D arrays through stacking into peapod-like complexes. Finally, as the formation of such nano-peapods strictly depends on nanoparticle dimensions, the peroxiredoxin template is used as a colloidal cut-off device to sort by size the encapsulated nanoparticles. These results open up possibilities in developing Prx-based methods to synthesize new advanced functional materials.

Abstract
As nanoparticles (NPs) enter into biological systems, they are immediately exposed to a variety and concentration of proteins. The physicochemical interactions between proteins and NPs are influenced by the surface properties of the NPs. To identify the effects of NP surface heterogeneity, the interactions between bovine serum albumin (BSA) and gold NPs (AuNPs) with similar chemical composition but different surface structures were investigated. Different interaction modes and BSA conformations were studied by dynamic light scattering, circular dichroism spectroscopy, fluorescence quenching and isothermal titration calorimetry (ITC). Depending on the surface structure of AuNPs, BSA seems to adopt either a "side-on" or an "end-on" conformation on AuNPs. ITC demonstrated that the adsorption of BSA onto AuNPs with randomly distributed polar and nonpolar groups was primarily driven by electrostatic interaction, and all BSA were adsorbed in the same process. The adsorption of BSA onto AuNPs covered with alternating domains of polar and nonpolar groups was a combination of different interactions. Overall, the results of this study point to the potential for utilizing nanoscale manipulation of NP surfaces to control the resulting NP-protein interactions.

Abstract
Graphene-based nanomaterials are particularly useful nanostructured materials that show great promise in biotechnology and biomedicine. Owing to their unique structural features, exceptional chemical, electrical, and mechanical properties, and their ability to affect the microenvironment of biomolecules, graphene-based nanomaterials are suitable for use in various applications, such as immobilization of enzymes. We present the current advances in research on graphene-based nanomaterials used as novel scaffolds to build robust nanobiocatalytic systems. Their catalytic behavior is affected by the nature of enzyme-nanomaterial interactions and, thus, the availability of methods to couple enzymes with nanomaterials is an important issue. We discuss the implications of such interactions along with future prospects and possible challenges in this rapidly developing area.

Abstract
A simple and robust protocol to maintain the structural feature of polymer-protein core-shell nanoparticles (PPCS-NPs) is developed based on the synergistic interactions between proteins and functional polymers. Using the self-assembly method, a broad range of proteins can be assembled to the selective water-insoluble polymers containing pyridine groups. The detailed analysis of the PPCS-NPs structure was conducted using FESEM and thin-sectioned TEM. The results illustrated that the protein molecules are located on the corona of the PPCS-NPs. While proteins are displacing between water and polymer to minimize the interfacial energy, the polymer offers a unique microenvironment to maintain protein structure and conformation. The proposed mechanism is based on a fine balance between hydrophobicity and hydrophilicity, as well as hydrogen bonding between proteins and polymer. The PPCS-NPs can serve as a scaffold to incorporate both glucose oxidase (GOX) and horseradish peroxidase (HRP) onto a single particle. Such a GOX-HRP bienzymatic system showed a ~20% increase in activity in comparison to the mixed free enzymes. Our method therefore provides a unique platform to preserve protein structure and conformation and can be extended to a number of biomolecules.

Abstract
![]()
We describe a novel epitope discovery
strategy for creating an
affinity agent/peptide tag pair. A synthetic polymer nanoparticle
(NP) was used as the “bait” to catch an affinity peptide
tag. Biotinylated peptide tag candidates of varied sequence and length
were attached to an avidin platform and screened for affinity against
the polymer NP. NP affinity for the avidin/peptide tag complexes was
used to provide insight into factors that contribute NP/tag binding.
The identified epitope sequence with an optimized length (tMel-tag)
was fused to two recombinant proteins. The tagged proteins exhibited
higher NP affinity than proteins without tags. The results establish
that a fusion peptide tag consisting of optimized 15 amino acid residues
can provide strong affinity to an abiotic polymer NP. The affinity
and selectivity of NP/tMel-tag interactions were exploited for protein
purification in conjunction with immobilized metal ion/His6-tag interactions
to prepare highly purified recombinant proteins. This strategy makes
available inexpensive, abiotic synthetic polymers as affinity agents
for peptide tags and provides alternatives for important applications
where more costly affinity agents are used.

Abstract
A technique was developed for preparing a novel material that consists of gold nanoparticles trapped within a fiber of unfolded proteins. These fibers are made in an aqueous solution that contains HAuCl4 and the protein, bovine serum albumin (BSA). By changing the ratio of gold to BSA in solution, two different types of outcomes are observed. At lower gold to BSA ratios (30-120), a purple solution results after heating the mixture at 80 °C for 4 h. At higher gold to BSA ratios (130-170), a clear solution containing purple fibers results after heating the mixture at 80 °C for 4 h. UV-Vis spectroscopy and light scattering techniques show growth in nanocolloid size as gold to BSA ratio rises above 100. Data indicate that, for the higher gold to BSA ratios, the gold is sequestered within the solid material. The material mass, visible by eye, appears to be an aggregation of smaller individual fibers. Scanning electron microscopy and transmission electron microscopy indicate that these fibers are primarily one-dimensional aggregates, which can display some branching, and can be as narrow as 400 nm in size. The likely mechanism for the synthesis of the novel material is discussed.

Abstract
Efficient labeling of protein-based targeting ligands with various cargos (drugs, imaging agents, nanoparticles, etc.) is essential to the fields of molecular imaging and targeted therapeutics. Many common bioconjugation techniques, however, are inefficient, nonstoichiometric, not site-specific, and/or incompatible with certain classes of protein scaffolds. Additionally, these techniques can result in a mixture of conjugated and unconjugated products, which are often difficult to separate. In this study, a bacterial sortase enzyme was utilized to condense targeting ligand purification and site-specific conjugation at the C-terminus into a single step. A model was produced to determine optimal reaction conditions for high conjugate purity and efficient utilization of cargo. As proof-of-principle, the sortase-tag expressed protein ligation (STEPL) technique was used to generate tumor-specific affinity ligands with fluorescent labels and/or azide modifications at high purity (>95%) such that it was not necessary to remove unconjugated impurities. Click chemistry was then used for the highly efficient and site-specific attachment of the azide-modified targeting ligands onto nanoparticles.

Abstract
Linear polymers have been considered the best molecular structures for the formation of efficient protein conjugates due to their biological advantages, synthetic convenience and ease of functionalization. In recent years, much attention has been dedicated to develop synthetic strategies that produce the most control over protein conjugation utilizing linear polymers as scaffolds. As a result, different conjugate models, such as semitelechelic, homotelechelic, heterotelechelic and branched or star polymer conjugates, have been obtained that take advantage of these well-controlled synthetic strategies. Development of protein conjugates using nanostructures and the formation of said nanostructures from protein-polymer bioconjugates are other areas in the protein bioconjugation field. Although several polymer-protein technologies have been developed from these discoveries, few review articles have focused on the design and function of these polymers and nanostructures. This review will highlight some recent advances in protein-linear polymer technologies that employ protein covalent conjugation and successful protein-nanostructure bioconjugates (covalent conjugation as well) that have shown great potential for biological applications.

Abstract
Magnetic iron oxide nanoparticles have raised much interest during the recent years due to their novel properties (superparamagnetism, high saturation field, blocking temperature, etc.) and potential applications in organic synthesis, biotechnology and finally in medicine. The medicinal applications include: controlled drug delivery systems (DDS), magnetic resonance imaging (MRI), magnetic fluid hyperthermia (MFH), macromolecules and pathogens separation, cancer therapy and so on. In this paper we would like to present the newest literature reports concerning usage of MNPs in medicinal diagnostics such as: - magnetic separations of DNA (immobilization, isolation, diagnosis of genetic disorders and detection of exogenous substances in the organisms) - magnetic immobilization of proteins (applications in biotechnology, medicine, and catalysis) - magnetic separations of pathogens (i.e. isolation of bacteria, detection of various pathogens) - magnetic resonance imaging (imaging contrast agents, lymphangiography).

Abstract
We report lysozyme self-assembly into nanotubes, under the effect of hydrolysis at pH 2 and 90 °C. We resolve the final steps of the fibrillation pathway, entailing the closure of multi-stranded helical ribbons into nanotubes, and we provide evidence of β-sheet arrangement within the nanotubes, demonstrating amyloid-like aggregation. Addition of chloroauric acid to the self-assembled structures can lead to generation of either gold single crystal nanoplatelets or gold nanoparticles (when a reducing agent is added) decorating the nanotube and ribbon surfaces. The crystal-based organic-inorganic hybrids further assemble into 3D "sandwiched" structures.

Abstract
C-type lectin receptors (CLRs) represent a large receptor family including collectins, selectins, lymphocyte lectins, and proteoglycans. CLRs share a structurally homologous carbohydrate-recognition domain (CRD) and often bind carbohydrates in a Ca²⁺-dependent manner. In innate immunity, CLRs serve as pattern recognition receptors (PRRs) and bind to the glycan structures of pathogens and also to self-antigens. In nature, the low affinity of CLR/carbohydrate interactions is overcome by multivalent ligand presentation at the surface of cells or pathogens. Thus, multivalency is a promising strategy for targeting CLR-expressing cells and, indeed, carbohydrate-based targeting approaches have been employed for a number of CLRs, including asialoglycoprotein receptor (ASGPR) in the liver, or DC-SIGN expressed by dendritic cells. Since CLR engagement not only mediates endocytosis but also influences intracellular signaling pathways, CLR targeting may allow for cell-specific drug delivery and also the modulation of cellular functions. Glyconanoparticles, glycodendrimers, and glycoliposomes were successfully used as tools for CLR-specific targeting. This review will discuss different approaches for multivalent CLR ligand presentation and aims to highlight how CLR targeting has been employed for cell specific drug delivery. Major emphasis is directed towards targeting of CLRs expressed by antigen-presenting cells to modulate immune responses.

Abstract
To understand which organic molecules are capable of binding to gold nanoparticles and/or inducing nanoparticle aggregation, we investigate the interaction of gold nanoparticles with small molecules and amino acids at variable pH. Dynamic Light Scattering (DLS) and ultraviolet-visible (UV-vis) spectra were measured on mixtures of colloidal gold with small molecules to track the progression of the aggregation of gold nanoparticles. We introduce the 522 to 435 nm UV-vis absorbance ratio as a sensitive method for the detection of colloidal gold aggregation, whereby we delineate the ability of thiol, amine, and carboxylic acid functional groups to bind to the surfaces of gold nanoparticles and investigate how combinations of these functional groups affect colloidal stability. We present models for mechanisms of aggregation of colloidal gold, including surface charge reduction and bridging linkers. For all molecules whose addition leads to the aggregation of gold nanoparticles, the aggregation kinetics were accelerated at acidic pH values. Colloidal gold is maintained only in the presence of anionic carboxyl groups, which are neutralized by protonation at lower pH. The overall reduced charge on the stabilizing carboxyl groups accounts for the accelerated aggregation at lower pH values.
