“…183 Due to distinct structural features, such as b-sheet rich conformations and exposed functional groups, amyloid fibrils have been reported for potential application in water purification. 48,[184][185][186][187][188] The ability of amyloids to sequester metals can be explored further for their potential as novel chelating agents and applications in environmental settings for the removal of metals. 48,184 For effective and specific metal removal, the metal-binding properties of amyloid-derived peptides can be enhanced through modification of the amino acid sequences or introduction of specific functional groups.…”

Lead (Pb 2+ ) is a ubiquitous pollutant. Membrane filtration represents one of the most common water treatment methods, but nanofiltration and ultrafiltration require high transmembrane pressure, while microfiltration has larger pore sizes than ions, making them unfavorable for direct ion removal at low cost. Selective and direct separation of Pb 2+ via membrane filtration at high efficiency without sacrificing the flux of clean water still remains challenging. Herein, inspired by the Pb 2+tolerable oleander that enriches and prevents Pb 2+ in roots from permeating the plant body, a smart Pb 2+ -adsorptive filtration membrane with a temperature-and ion-tunable water gate was prepared by loading dual-responsive poly(N-isopropylacrylamidoco-acrylamido-benzo-18-crown-6) (PNB-5-20) microgels onto a commercial membrane. The PNB-5-20 microgel exhibits pronounced temperature-responsive swelling/deswelling (hydrodynamic diameter, 650−330 nm) with a volume phase transition temperature (VPTT) at ∼33 °C. Moreover, the microgel shows a high Pb 2+adsorption capacity (q max , 85.4 mg/g) and good selectivity (distribution coefficient K d ∼ 1000 mL/g) thanks to its complexation with the crown ether, as well as good Pb 2+ responsiveness, having the VPTT positively shifted to 40 °C in the presence of Pb 2+ with enhanced swelling behaviors. Functionalized with PNB-5-20, the smart membrane integrates Pb 2+ detection, adsorption, and tunable water drainage in a single device. The membrane selectively recognizes Pb 2+ in the polluted water with the gates in membrane pores switching from "open" to "closed", intercepting and adsorbing Pb 2+ with water permeation reduced. Once purified, the gates can be "re-opened" by increasing the temperature. Construction of such an intelligent membrane filtration device with a tunable water gate and excellent Pb 2+ recognition and adsorption performance will greatly simplify the remediation of Pb 2+ -polluted water.

Many food proteins can be assembled into nanofibrils under pH conditions far from the isoelectric point and with a low ionic strength by heating them for a long period. These food protein nanofibrils (FPN) have outstanding functional and biological properties and are considered sustainable biomaterials in many fields. In this study, we review the recent developments in FPN gels and introduce the key factors in promoting food protein self-assembly in order to create functional gels. The major variables discussed are the morphology of nanofibrils, protein concentration, heating time, and the type and concentration of salts. We also highlight current advances in the formation and properties of different types of FPN gels. In addition, the various applications of FPN gels in bioactive and nutrient delivery, adsorbents for CO2 and toxic pollutants, cell scaffolding biomaterials, biosensors, and others are introduced and discussed.
