“…This feature was very useful for pressure-driven filtration separation . According to the interfacial formation mechanism, the oil/water interface area was able to determine the size of the membrane and thereby a large-area membrane can be easily obtained at the laboratory scale using this method, which has proven to be effective in the fabrication of the film with a diameter as large as 3 in. (Figure S7).…”

Developing the ultrathin membranes for highperformance separation still faces the challenge of both high permeance and selectivity. Herein, a large-area protein membrane was fabricated by the interfacial self-assembly of bovine serum albumin (BSA) and surfactants at the oil/water interface of emulsions. Benefiting from the ultrathin thickness and unique protein-surrounded tortuous channels, the membrane displays ultrahigh permeation flux and selective sieving capability for various molecules ranging from small dye molecules to proteins based on a dual filtration mechanism. More importantly, the rejection precision can also be reversibly regulated by the folding/ unfolding transition of proteins to control the effective pore size of transport channels, even under a pressure-driven condition. This dynamically tunable ultrathin protein membrane combines the advantages of high permeance, selectivity, controllability, recyclability, and mechanical stability, which may create new opportunities for advanced applications in extended fields.

“…The deposited films are free of aggregates and show positive zeta potential in acidic and neutral pH conditions which can induce hydrophilicity to the protein. However, AFM and TEM analysis indicates the deposited nanofilm composed of aggregates of nanoparticles with average diameter of 50 nm (See Figure B and C) . The appearance of the nanoparticle can be closely correlated with the lysozyme phase transition process, which is dominated by the aggregation and unfolding of the protein (See the Figure ).…”

“…These transparent, high surface area based coating shows better antibacterial property hence can be a operable surface modifier for the polymer membranes . Lysozyme is a non‐toxic and recognized by food and drug administration and is available from egg whites, animals and plant cells . The lysozyme is a low‐cost antibiotic enzyme, which can undergo a phase transition in the presence of tris(2‐carboxyethyl)phosphine (TCEP) in an ambient aqueous solution.…”

“…The lysozyme is a low‐cost antibiotic enzyme, which can undergo a phase transition in the presence of tris(2‐carboxyethyl)phosphine (TCEP) in an ambient aqueous solution. The phrase “phase transition” indicates the solution and aggregation of proteins ,. TCEP breaks the disulphide bond and makes thiol group available for the next biochemical reactions and site‐specific protein immobilization, nucleation and induce assembling of lysozymes.…”

Recent Advances in Preparation of Porous Polymeric Membranes by Unique Techniques and Mitigation of Fouling through Surface Modification

In this review, modern techniques for the membrane preparation including 3D printing, phase separation micro molding, selective etching and self‐assembled and non‐solvent induced phase separation (SNIPS) are discussed. The article also takes account of traditional membrane preparation techniques such as phase inversion, sintering, track etching and electrospinning. Although, there is plenty of literature exists on the preparation and tailoring of membrane properties, there are still challenges to develop and establish a reliable membrane fabrication method with high flux, selectivity and anti‐fouling properties. Hydrophobic polymers are more prone to foul due to its low surface energy compared to hydrophilic polymers. Fouling resistance of membrane against microbes and proteins had been significantly improved by the use of nanoparticles, and modification with hydrophilic polymers. Mussel‐inspired coating and amyloid proteins are also recently found to have excellent antibacterial activity are also reviewed. Hence, a broad understanding of structure and properties is essential for further development and progress in membrane technology for water purification.

“…Yang et al. have explored the conformation changes of lysozyme after breaking down the S−S bond to induce heterogeneous nucleation and assembly [197] . The assembled lysozyme fibrils spontaneously concentrate at both the solid‐water and water−air interfaces, and the films formed at this interface could easily be converted into free‐floating films, transferred to the surface of a hydrogel, and then contact printed onto a water‐sensitive substrate.…”

Supramolecular self‐assembled structures, based on protein−protein interactions, have garnered widespread interest as prospective functional bionanomaterials. Possessing unique properties, proteins have been widely investigated in the last years, due to their capability to form a diversity of natural and artificially designed zero‐, one‐, two‐ and three‐dimensional assemblies. These structures laid the basis for bionanomaterials design, including films, foams, gels, and others, with widespread applications in electronics, biomedicine, and environmental sciences. In this context, the present review is devoted to revealing the diversity of protein assemblies and related bionanomaterials. Special interest is paid to recent advances and new trends in functional amyloids and fibrillar silk‐based self‐assembling architectures, as well as their current and potential applications. We emphasize the protein nanostructures’ diversity for the future design of functional protein‐based materials.
