“…The I–V curve (linear voltammogram) in Figure a shows that the conductivity of PS is higher than those of PSN2 and PSN4. The derivative represents the location of the valence band and conduction band of the protein thin film. , The band gap in PS is lower than that of PSN2 and PSN4 as presented in Table . If the band gap is lower, it indicates a facile electron transfer in the material under an applied electric field.…”

The protein extracted from the discarded eye lenses postcataract surgery, referred to as the cataractous eye protein isolate (CEPI), is employed as a polymer matrix for the construction of solid polymer electrolyte species (SPEs). SPEs are expected to be inexpensive, conductive, and mechanically stable in order to be economically and commercially viable. Environmentally, these materials should be biodegradable and nontoxic. Taking these factors into account, we investigated the possibility of using a discarded protein as a polymer matrix for SPEs. Natural compounds sorbitol and sinapic acid (SA) are used as the plasticizer and cross-linker, respectively, to tune the mechanical as well as electrochemical properties. The specific material formed is demonstrated to have high ionic conductivity ranging from ∼2 × 10 −2 to ∼8 × 10 −2 S cm −1 . Without the addition of any salt, the ionic conductivity of sorbitol-plasticized non-cross-linked CEPI is ∼7.5 × 10 −2 S cm −1 . Upon the addition of NaCl, the conductivity is enhanced to ∼8 × 10 −1 S cm −1 . This study shows the possibility of utilizing a discarded protein CEPI as an alternative polymer matrix with further potential for the construction of tunable, flexible, recyclable, biocompatible, and biodegradable SPEs for flexible green electronics and biological devices.

Two glyco-probes, GFP and GFN, which are derived from the condensation of 3-acetyl-5-C-(2,3-dihydroxy-1,4-anhydro-β-D-erythro-tetrofuranosyl)-2-methylfuran with benzaldehyde and 1-naphthaldehyde, respectively, are designed and synthesized. Of these two probes, GFP displays a selective and sensitive switch-on fluorescence response towards bovine serum albumin in phosphate-buffered saline over a wide pH range. Moreover, the fluorescence of this probe displays a good linear relationship with the bovine serum albumin concentration ranging from 0 to 0.8 mg/mL, and has a limit of detection as low as 3.7 nM. The stoichiometric ratio of bovine serum albumin /GFP is 1:1. This research paves the way for the development of glyco-probes for bovine serum albumin sensing.

“…The Tauc relation, Figure 3b, reveals direct band gaps of 2.75 ± 0.1 eV for Album/FLG and 1.6 ± 0.1 eV for the composites containing iron. The band gap of 2.75 ± 0.1 eV in Album/FLG matches with the values measured/calculated for ferritins or BSA (0.8 to 2.6 eV and 1.48 eV) 41,42 and can be easily modified by doping and in this case the doping with FLG carbon. On the other hand, a doping of FLG with adsorbed BSA and additional oxygen can enhance the band gap of FLG in a significant manner.…”

To address energy requirements via an optimally sustainable way is of high interest. A ternary hybrid based on natural protein, few layer graphene, and a nonprecious metal component is obtained by a rapid and green method bypassing high-temperature calcination. Its significant activity in H 2 production via photoreforming of methanol is related to the factors combining the nanosized related quantum confinement effect and small band gap, increased conduction band edge, and enhanced reducibility of Fe x O 3 nanoparticles (size up to 2 nm). The albumin homogeneously decorating the FLG surface helps in the catalyst dispersion, reduction of photogenerated charge recombination, and MeOH adsorption. Fe x O 3 /Album/FLG shows great photostability and superior activity to the TiO 2 based catalysts of reference.
