Abstract
A peanut-like hollow silica (denoted as p-l-hSiO2) adsorbent is prepared in a facile method, which is composed of several silica nanospheres and has an average diameter of 22 nm, with thickness of 5 nm. Its Brunauer–Emmett–Teller (BET) surface area, pore volume and pore size are 258.9 m2 g−1, 1.56 cm3 g−1 and 3.9 nm, respectively. Then the afforded p-l-hSiO2/GSH adsorbent is applied to purify glutathione S-transferases-tagged (denoted as GST-tagged) proteins. It is found that the p-l-hSiO2 adsorbent exhibits a specific adsorption, a high binding capacity (6.80 mg g−1), good recycling performance and high recovery (90.1%) to the target proteins, showing promising potential for the affinity separation of GST-tagged proteins. Peanut-like Sn-doped hollow silica adsorbent is prepared in a facile method, which exhibits a specific adsorption, a high binding capacity , good recycle performance and high recovery to the GST-tagged proteins.![]()

Abstract
Sugar chain immobilized polymer particles having both magnetic and fluorescent properties can be expected to be useful in a wide variety of biomedical applications such as the detection, separation, and purification of proteins, viruses, or bacteria, because sugar chains specifically adsorb them. Since high magnetic responsiveness is required for such applications, we attempted to fabricate core-shell particles consisting of a submicron-sized magnetic core and a thin polymer shell (nano- to dozens of nanometers thick) that incorporates a fluorescent dye, with sugar molecules immobilized on the surface. Soap-free emulsion polymerization using methyl methacrylate (MMA) monomer and potassium persulfate (KPS) initiator in the presence of aminopropyltrimethoxysilane-treated Ni particles, octyl-β-D-glucopyranoside (octyl-glc), and rhodamine B (RhB) produced a glucose-immobilized fluorescent PMMA thin shell on a Ni particle (Ni/PMMA/RhB/octyl-glc). Electrostatic interaction was used both to incorporate RhB into the PMMA shell and to coat the Ni core with the PMMA-RhB shell. Glucose was immobilized on the PMMA shell by embedding a hydrophobic octyl group derived from octyl-glc in the PMMA matrix, and the resulting sugar-immobilized PMMA shell was able to adsorb protein (concanavalin A; a protein that specifically adsorbs glucose). The resulting Ni/PMMA/RhB/octyl-glc particles were well-dispersed in water, detected by highly sensitive fluorescence techniques, and could be collected by a magnet within 10 sec. They are expected to be applied to detect biological substances such as various proteins and viruses by changing the glucose moiety of the particle surface to other functional glycans.

Abstract
Purpose: The growing prevalence of multidrug-resistant (MDR) bacteria makes it clinically urgent to develop an agent able to detect and treat infections simultaneously. Silver has served as a broad-spectrum antimicrobial since ancient times but suffers from major challenges such as moderate antimicrobial activity, nonspecific toxicity, and difficulty to be visualized in situ. Here, we propose a new photoactive silver nanoagent that relies on a photosensitizer-triggered cascade reaction to liberate Ag+ on bacterial surfaces exclusively, allowing the precise killing of MDR bacteria. Additionally, the AgNP core acts as a backgroundless surface-enhanced Raman scattering (SERS) substrate for imaging the distribution of the nanoagents on bacterial surfaces and monitoring their metabolic dynamics in the infection sites. Methods: In this strategy, the photoactive antibacterial AgNP was decorated with photosensitizers (Chlorin e6, Ce6) and Raman reporter (4-Mercaptobenzonitrile, 4-MB) to provide new opportunities for clinically monitoring and fighting MDR bacterial infections. Upon 655 nm laser activation, the Ce6 molecules produce ROS efficiently, triggering the rapid release of Ag+ from the AgNP core to kill bacteria. Poly[4-O-(α-D-glucopyranosyl)-D-glucopyranose] (GP) was introduced as bacteria-specific targeting ligands. SERS spectra of the prepared GP-Ce6/MB-AgNPs were recorded after injecting for 0.5, 4, 8, 12, 24, and 48 h to track the dynamic metabolism of the nanoagents and thus guiding the antibacterial therapy. Results: This new antimicrobial strategy exerts a dramatically enhanced antibacterial activity. The in vitro antibacterial efficiencies of this non-antibiotic technique were up to 99.6% against Methicillin-resistant Staphylococcus aureus (MRSA) and 98.8% against Escherichia coli (EC), while the in vivo antibacterial efficiencies for MRSA- and Carbapenem-resistant Pseudomonas aeruginosa (CRPA)-infected mice models were 96.8% and 93.6%, respectively. Besides, backgroundless SERS signal intensity of the wound declined to the level of normal tissue until 24 h, indicating that the nanoagents had been completely metabolized from the infected area. Conclusion: Given the backgroundless monitoring ability, high antibacterial efficacy, and low toxicity, the photoactive cascading agents would hold great potential for MDR-bacterial detection and elimination in diverse clinical settings.

Abstract
In this work, we presented a facile elution-free method for ultrasensitive enrichment of glycopeptides using two kinds of novel Ce-metal-organic frameworks (Ce-MOF) post-modified with hyaluronic acid (Ce-MOF@HA) and glutamic acid (Ce-MOF@Glu). Both of the synthesized materials remained stable in the loading buffer to enrich glycopeptides selectively and degrade in the eluent to release captured glycopeptides. Due to the dissolution of materials, the elution step of the enrichment process is omitted, resulting in an extremely high sensitivity (detection limit, 0.5 fmol/μL). Meanwhile, Ce-MOF@HA and Ce-MOF@Glu also possessed excellent selectivity with molar ratios of IgG and BSA digests being 1:1000 and 1:500, respectively. Noticeably, the practical applicability of the obtained materials was inspected by analyzing the glycopeptides enriched from human serum (2 μL) by nano-LC-MS, in which 434 N-glycopeptides from 182 N-glycoproteins (by Ce-MOF@HA) and 328 N-glycopeptides from 135 N-glycoproteins (by Ce-MOF@Glu) were detected, respectively. This work provides a new method to simplify the process of glycopeptides enrichment and also paves a novel way for the enrichment of trace targets from complex matrices.

Abstract
The promising potential of magnetic polymer microspheres in various biomedical applications has been frequently reported. However, the surface hydrophilicity of superparamagnetic iron oxide nanoparticles (SPIONs) usually leads to poor or even failed encapsulation of SPIONs in hydrophobic polymer microspheres using the emulsion method. In this study, the stability of SPIONs in poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) solution was significantly increased after surface modification with lauric acid. As a result, magnetic PHBV microspheres with high encapsulation efficiencies (71.0-87.4%) were prepared using emulsion-solvent extraction/evaporation method. Magnetic resonance imaging (MRI) showed significant contrast for the magnetic PHBV microspheres. The toxicity of these magnetic PHBV microspheres towards human T-lymphoma suspension cells and adherent colon carcinoma HT-29 cells was investigated using flow cytometry, and they were shown to be non-toxic in a broad concentration range. A model drug, tetracycline hydrochloride, was used to demonstrate the drug delivery capability and to investigate the drug release behavior of the magnetic PHBV microspheres. The drug was successfully loaded into the microspheres using lauric acid-coated SPIONs as drug carrier, and was released from the microspheres in a diffusion controlled manner. The developed magnetic PHBV microspheres are promising candidates for biomedical applications such as targeted drug delivery and MRI.

Abstract
As a facile method to prepare hydrophilic polymeric microspheres, reflux precipitation polymerization has been widely used for preparation of polymer nanogels. In this article, we synthesized a phthalamide-protected N-aminooxy methyl acrylamide (NAMAm-p) for preparation of alkoxyamine-functionalized polymer composite microspheres via reflux precipitation polymerization. The particle size and functional group density of the composite microspheres could be adjusted by copolymerization with the second monomers, N-isopropyl acrylamide, acrylic acid or 2-hydroxyethyl methacrylate. The resultant microspheres have been characterized by TEM, FT-IR, TGA and DLS. The experimental results showed that the alkoxyamine group density of the microspheres could reach as high as 1.49 mmol/g, and these groups showed a great reactivity with ketone/aldehyde compounds. With the aid of magnetic core, the hybrid microspheres could capture and magnetically isolate glycopeptides from the digested mixture of glycopeptides and non-glycopeptides at a 1:100 molar ratio. After that, we applied the composite microspheres to profile the glycol-proteome of a normal human serum sample, 95 unique glycopeptides and 64 glycoproteins were identified with these enrichment substrates in a 5 μL of serum sample.

Abstract
While much effort has been made to prepare magnetic microspheres (MMs) with surface moieties that bind to affinity tags or fusion partners of interest in the recombinant proteins, it remains a challenge to develop a generic platform that is capable of incorporating a variety of capture ligands by a simple chemistry. Herein, we developed core-shell structured magnetic microspheres with a high magnetic susceptibility and a low nonspecific protein adsorption. Surface functionalization of these MMs with azide groups facilitates covalent attachment of alkynylated ligands on their surfaces by "click" chemistry and creates a versatile platform for selective purification and immobilization of recombinant proteins carrying corresponding affinity tags. The general applicability of the approach was demonstrated in incorporating four widely used affinity ligands with different reactive groups (-CHO, -SH, -COOH, and -NH2) onto the MMs platform for purification and immobilization of targeted proteins. The azide-functionalized MMs would be applicable for a variety of ligands and substrates that are amenable to alkynylation modification.

Abstract
The growing need for more efficient separation techniques still dominates downstream processing of biomolecules, thus encouraging the continuous development of advanced nanomaterials. In this paper we present an improved process for recovering recombinant histidine tagged green fluorescent protein from an E. coli cell lysate. Superparamagnetic core-shell nanocarriers are functionalized with a pentadentate chelate affinity ligand and then loaded with metal ions (Cu(2+), Ni(2+), or Zn(2+)). The separation process yields high binding capacity (250 mg/g), good selectivity, purity >98%, good recyclability with 90% capacity after 9 cycles, and long-term stability. We determined the main physical properties of the magnetite-based nanoparticles such as saturation magnetization (59 A m(2)/kg), primary particle diameter (22 ± 4 nm), and specific surface area (89 m(2)/g). Our results show that this material is a promising tool for bioseparation applications. One special focus of the work includes analyzing the changes in the hydrodynamic size distribution using dynamic light scattering and transmission electron microscopy. We relate these effects to different interaction levels in the system and discuss how the stronger aggregation of the magnetite core is the main limiting factor for the separation yield, leading to a considerable decrease in the number of metal ions available for biomolecular capture. Otherwise weaker interactions lead instead to agglomeration effects that have no impact on the binding capacity of the system. The simple relation between the size of the aggregated units and the size of the primary particles corresponds approximately to the relation between the number of existing binding sites and the actual protein binding in the separation process. Compared with that, the effect of steric hindrance among proteins is of less significance.
