Abstract
Solid-binding peptides are a simple and versatile tool for the non-covalent modification of solid material surfaces, and a variety of peptides have been developed by reference to natural proteins or de novo design. Here, for the first time, we report the discovery of a bicyclic peptide targeting the heterogeneous material polypropylene by combining phage display technology and next-generation sequencing. We find that the enrichment properties of bicyclic peptides capable of binding to polypropylene are distinct from linear peptides, as reflected in amino acid abundance and a trend toward negative net charges and high hydrophobicity. The selected bicyclic peptide has a higher binding affinity for polypropylene compared with a previously reported linear peptide, enabling the hydrophilic and adhesive properties of the polypropylene to be more effectively enhanced. Our work paves the way for the exploration and utilization of conformational-restricted cyclic peptides as a new family of functionally evolvable agents for material surface modification.

Abstract
Osteogenic peptides are often introduced to improve biological activities and the osteogenic ability of artificial bone materials as an effective approach. Covalent bindings between the peptide and the host material can increase the molecular interactions and make the functionalized surface more stable. However, covalent bindings through different functional groups can bring different effects on the overall bioactivities. In this study, carboxyl and amino groups were respectively introduced onto carbon nanotubes, a nanoreinforcement for synthetic scaffold materials, which were subsequently covalently attached to the RGD/BMP-2 osteogenic peptide. MC3T3-E1 cells were cultured on scaffolds containing peptide-modified carbon nanotubes. The results showed that the peptide through the amino group binding could promote cell functions more effectively than those through carboxyl groups. The mechanism may be that the amino group could bring more positive charges to carbon nanotube surfaces, which further led to differences in the peptide conformation, protein adsorption, and targeting osteogenic effects. Our results provided an effective way of improving the bioactivities of artificial bone materials by chemically binding osteogenic peptides.

Abstract
The functionalization of polymer surfaces by polymer-binding peptides offers tremendous opportunities for directed immobilization of enzymes, bioactive peptides, and antigens. The application of polymer-binding peptides as adhesion promoters requires reliable and stable binding under process conditions. Molecular modes of interactions between material surfaces, peptides, and solvent are often not understood to an extent that enables (semi-) rational design of polymer-binding peptides, hindering the full exploitation of their potential. Knowledge-gaining directed evolution (KnowVolution) is an efficient protein engineering strategy that facilitates tailoring protein properties to application demands through a combination of directed evolution and computational guided protein design. A single round of KnowVolution was performed to gain molecular insights into liquid chromatography peak I peptide, 47 aa (LCI)-binding to polypropylene (PP) in the presence of the competing surfactant Triton X-100. KnowVolution yielded a total of 8 key positions (D19, S27, Y29, D31, G35, I40, E42, and D45), which govern PP-binding in the presence of Triton X-100. The recombination of two of the identified amino acid substitutions (Y29R and G35R; variant KR-2) yielded a 5.4 ± 0.5-fold stronger PP-binding peptide compared to LCI WT in the presence of Triton X-100 (1 mM). The LCI variant KR-2 shows a maximum binding capacity of 8.8 ± 0.1 pmol/cm² on PP in the presence of Triton X-100 (up to 1 mM). The KnowVolution approach enables the development of polymer-binding peptides, which efficiently coat and functionalize PP surfaces and withstand surfactant concentrations that are commonly used, such as in household detergents.

Abstract
Proteins have been the subject of electrochemical studies. It is possible to apply electrochemical techniques to obtain information about their structure due to the presence of five electroactive amino acids that can be oriented to the outside of the peptidic chain. These amino acids are L-Tryptophan (L-Trp), L-Tyrosine (L-Tyr), L-Histidine (L-His), L-Methionine (L-Met) and L-Cysteine (L-Cys); their electrochemical behavior being subject of extensive research, but it is still controversial. No spectroscopic investigations have been reported on L-Trp, and due to the short life time of the intermediates, ex situ techniques cannot be employed, leading to a never-ending discussion about possible intermediates. In the L-Tyr and L-His cases, spectroelectrochemical studies were performed and different intermediates were observed, suggesting that some intermediates may be observed under specific conditions, as proposed for L-Cys. This amino acid is the most interesting among the electroactive ones because of the presence of a thiol moiety at its side chain, leading to a wide range of oxidation states. It can adsorb onto surfaces of different crystallographic orientation in stereoselective conformation, modifying the surface for different applications.as a surface engineering tool since it plays the role of as an anchor for the growing of nanocrystals inside proteic templates.

Abstract
Engineered peptides capable of binding to silica have been used to provide contrast in chemical force microscopy and tested for their capacity to selectively capture silica nanoparticles (NPs). Gold coated atomic force microscopy (AFM) microcantilevers with integrated tips and colloidal probes were functionalized with engineered peptides through a thiol group of a terminal cysteine which was linked via a glycine trimer to a 12-mer binding sequence. The functionalized probes demonstrated a significantly increased binding force on silicon oxide areas of a gold-patterned silicon wafer, whereas plain gold probes, and those functionalized with a random permutation of the silica binding peptide motif or an all-histidine sequence displayed similar adhesion forces to gold and silicon oxide. As the functionalized probes also allowed contact mode imaging subsequently to the adhesion mapping, also the associated friction contrast was measured and found to be similar to the adhesion contrast. Furthermore, the adsorption of silica NPs onto planar gold surfaces functionalized in the same manner was observed to be selective. Notably, the surface coverage with silica NPs was found to decrease with increasing pH, implying the importance of electrostatic interactions between the peptide and the NPs. Finally, the adsorption of silica NPs was monitored via the decrease in fundamental resonance frequency of an AFM microcantilever functionalized with silica binding peptides.

Abstract
We describe a new affinity purification tag called Car9 that confers proteins to which it is fused micromolar affinity for unmodified silica. When appended to the C-terminus of GFPmut2 through a flexible linker, Car9 promotes efficient adsorption to silica gel and the fusion protein can be released from the particles by incubation with L-lysine. Using a silica gel column and the lysine elution approach in fast protein liquid chromatography (FPLC) mode, Car9-tagged versions of GFPmut2, mCherry and maltose binding protein (MBP) can be recovered from clarified lysates with a purity of 80-90%. Capitalizing on silica's ability to handle large pressure drops, we further show that it is possible to go from cell lysates to purified protein in less than 15 min using a fully disposable device. Finally, we demonstrate that the linker-Car9 region is susceptible to proteolysis by E. coli OmpT and take advantage of this observation to excise the C-terminal extension of GFPmut2-Car9 by incubating purified fusion protein with cells that overproduce the outer membrane protease OmpT. The set of strategies described herein, should reduce the cost of affinity purification by at least 10-fold, cut down purification times to minutes, and allow for the production of proteins with native (or nearly native) termini from their C-terminally-tagged versions.

Abstract
Designer proteins that incorporate solid-binding peptides hold promise to control the nucleation, growth, morphology, and assembly of inorganic phases under mild conditions of temperature and pressure. However, protein-aided nanofabrication remains more art than science and some materials can only be synthesized at temperatures that cause most mesophilic proteins to unfold. Using zinc oxide (ZnO) synthesis at 70°C as case study, we show here that seemingly unimportant variables, such as the carry-over concentration of Tris buffer and the "empty" host protein scaffold can exert a significant influence on materials morphology. We also show that, once well-controlled conditions are established, thermodynamic predictions and adsorption isotherms are powerful tools to understand how various ZnO-binding sequence inserted within the thermostable framework of Escherichia coli thioredoxin A (TrxA) affect inorganic morphogenesis.

Abstract
Calcium phosphate (CaP) polymorphs are nontoxic, biocompatible and hold promise in applications ranging from hard tissue regeneration to drug delivery and vaccine design. Yet, simple and robust routes for the synthesis of protein-coated CaP nanoparticles in the sub-100 nm size range remain elusive. Here, we used cell surface display to identify disulfide-constrained CaP binding peptides that, when inserted within the active site loop of Escherichia coli thioredoxin 1 (TrxA), readily and reproducibly drive the production of nanoparticles that are 50-70 nm in hydrodynamic diameter and consist of an approximately 25 nm amorphous calcium phosphate (ACP) core stabilized by the protein shell. Like bone and enamel proteins implicated in biological apatite formation, peptides supporting nanoparticle production were acidic. They also required presentation in a loop for high-affinity ACP binding as elimination of the disulfide bridge caused a nearly 3-fold increase in hydrodynamic diameters. When compared to a commercial aluminum phosphate adjuvant, the small core-shell assemblies led to a 3-fold increase in mice anti-TrxA titers 3 weeks postinjection, suggesting that they might be useful vehicles for adjuvanted antigen delivery to dendritic cells.

Abstract
Increasing interest in bio-interfaces for medical, diagnostic, or biotechnology applications has highlighted the critical scientific challenge behind both the understanding and control of protein-solid surface interactions. In this context, this Account focuses on the molecular-level characterization of the interactions of peptides, ranging in size from a few amino acids to long sequences, with metal and oxide surfaces. In this Account, we attempt to fill the gap between the well-known basic studies of the interaction of a single amino acid with well-defined metal surfaces and the investigations aimed at controlling biocompatibility or biofilm growth processes. We gather studies performed with surface science tools and macroscopic characterization techniques along with those that use modeling methods, and note the trends that emerge. Sulfur drives the interaction of cysteine-containing peptides with metal surfaces, particularly gold. Moreover, intermolecular interactions, such as hydrogen bonds may induce surface self assembly and chiral arrangements of the peptide layer. Depending on the solvent pH and composition, carboxylates or amino groups may also interact with the surface, which could involve conformational changes in the adsorbed peptide. On oxide surfaces such as titania or silica, researchers have identified carboxylate groups as the preferential peptide binding groups because of their strong electrostatic interactions with the charged surface. In high molecular weight peptides, systematic studies of their interaction with various oxide surfaces point to the preferential interaction of certain peptide sequences: basic residues such as arginine assume a special role. Researchers have successfully used these observations to synthesize adhesive sequences and initiate biomineralization. Studies of the interaction of peptides with nanoparticles have revealed similar binding trends. Sulfur-containing peptides adhere preferentially to gold nanoparticles. Peptides containing aromatic nitrogen also display a high affinity for various inorganic nanoparticles. Finally, we describe a novel class of peptides, genetically engineered peptides for inorganics (GEPIs), which are selected from a phage display protocol for their high binding affinity for inorganic surfaces. Extended investigations have focused on the mechanisms of the molecular binding of these peptides to solid surfaces, in particular the high binding affinity of some sulfur-free sequences of GEPIs to gold or platinum surfaces. We expect that this clearer view of the possible preferential interactions between peptides and inorganic surfaces will facilitate the development of new, more focused research in various fields of biotechnology, such as biocompatibility, biomimetics, or tissue engineering.

Abstract
Quantum dots (QDs) are a powerful alternative to organic dyes and fluorescent proteins for biological and biomedical applications. These semiconductor nanocrystals are traditionally synthesized above 200 degrees C in organic solvents using toxic and costly precursors, and further steps are required to conjugate them to a biological ligand. Here, we describe a simple, aqueous route for the one-pot synthesis of antibody-derivatized zinc sulfide (ZnS) immuno-QDs. In this strategy, easily expressed and purified fusion proteins perform the dual function of nanocrystal mineralizers through ZnS binding sequences identified by cell surface display and adaptors for immunoglobin G (IgG) conjugation through a tandem repeat of the B domain of Staphylococcus aureus protein A. Although approximately 4.3 nm ZnS wurtzite cores could be biomineralized from either zinc chloride or zinc acetate precursors, only the latter salt gives rise to protein-coated QDs with long shelf life and narrow hydrodynamic diameters (8.8 +/- 1.4 nm). The biofabricated QDs have a quantum yield of 2.5% and blue-green ensemble emission with contributions from the band-edge at 340 nm and from trap states at 460 and 665 nm that are influenced by the identity of the protein shell. Murine IgG(1) antibodies exhibit high affinity (K(d) = 60 nM) for the protein shell, and stable immuno-QDs with a hydrodynamic diameter of 14.1 +/- 1.3 nm are readily obtained by mixing biofabricated nanocrystals with human IgG.

Abstract
Peptides with specific binding affinity to inorganic materials bridge biological systems with synthetic inorganic materials. Many inorganic-binding peptides were isolated using combinatorial peptide libraries without a good understanding of the interaction mechanism, which thus hinders the practical application of these peptides. Besides the amino acid composition, peptides' structure (e.g., cyclic structure constrained by disulfide bond) is believed to play an important role in their binding behavior. A cyclic peptide STB1 (-CHKKPSKSC-) was previously identified to electrostatically bind to TiO2 and SiO2. In the present study, the binding behavior (affinity and conformation) of STB1 and its linear version LSTB1 (-AHKKPSKSA-) on a TiO2 or SiO2 surface was investigated in three different contexts (i.e., free peptides, phage particles displaying peptides, and LacI-peptide fusion protein) using quartz crystal microbalance with energy dissipation measurement (QCM-D). The binding kinetics of STB1 and LSTB1 in the context of fusion protein to either metal oxide was quantitatively analyzed. LSTB1 showed similar binding behavior on both TiO2 and SiO2 surfaces. In the context of phage-displayed and LacI-hosted peptides, STB1 was found to have weaker binding affinity than LSTB1 for either metal oxide, but it was able to distinguish between SiO2 and TiO2. This is probably because LSTB1 has a much more flexible structure than STB1, as shown by the molecular dynamics simulation. The structural flexibility of LSTB1 enables it to explore a wider range of conformations to maximize its interaction with TiO2 and SiO2.

Abstract
In examining adsorption of a few selected single amino acids on Au and Pd cluster models by density functional theory calculations, we have shown that specific side-chain binding affinity to the surface may occur because of a combination of effects, including charge transfer. Larger binding was calculated at the Pd interface. In addition, the interplay between amino acid solvation and adsorption at the interface was considered from first principles. This analysis serves as the first step toward gaining a more accurate understanding of specific interactions at the interface of biological-metal nanostructures than has been attempted in the past.

Abstract
Despite extensive recent reports on combinatorially selected inorganic-binding peptides and their bionanotechnological utility as synthesizers and molecular linkers, there is still only limited knowledge about the molecular mechanisms of peptide binding to solid surfaces. There is, therefore, much work that needs to be carried out in terms of both the fundamentals of solid-binding kinetics of peptides and the effects of peptide primary and secondary structures on their recognition and binding to solid materials. Here we discuss the effects of constraints imposed on FliTrx-selected gold-binding peptide molecular structures upon their quantitative gold-binding affinity. We first selected two novel gold-binding peptide (AuBP) sequences using a FliTrx random peptide display library. These were, then, synthesized in two different forms: cyclic (c), reproducing the original FliTrx gold-binding sequence as displayed on bacterial cells, and linear (l) dodecapeptide gold-binding sequences. All four gold-binding peptides were then analyzed for their adsorption behavior using surface plasmon resonance spectroscopy. The peptides exhibit a range of binding affinities to and adsorption kinetics on gold surfaces, with the equilibrium constant, Keq, varying from 2.5x10(6) to 13.5x10(6) M(-1). Both circular dichroism and molecular mechanics/energy minimization studies reveal that each of the four peptides has various degrees of random coil and polyproline type II molecular conformations in solution. We found that AuBP1 retained its molecular conformation in both the c- and l-forms, and this is reflected in having similar adsorption behavior. On the other hand, the c- and l-forms of AuBP2 have different molecular structures, leading to differences in their gold-binding affinities.
