Circular valorization of Hypericum perforatum biomass into CuO-lignin and CuO-cellulose bionanocomposites for mitigating copper nanotoxicity in plants.

We present a circular biomass valorisation strategy for the synthesis of CuO-based nanocomposites (NCs) using Hypericum perforatum L. In this approach, H. perforatum serves a dual purpose: its phytochemicals are used to synthesize CuO nanoparticles (NPs), while the remaining biomass is used to extract lignin and cellulose.

Presenting B-DNA as macromolecular crowding agent to improve efficacy of cytochrome c under various stresses.

Existence of numerous biomolecules results in biological fluids to be extremely crowded. Thus, Macromolecular crowding is an essential phenomenon to sustain active conformation of proteins in biological systems. Herein, double helical deoxyribonucleic acid (B-DNA) is presented for the first time as a biomacromolecular crowding system for sustainable packaging of cytochrome c (Cyt C).

Designing biopolymer-based artificial peroxidase for oxidative removal of dibenzothiophene from a model diesel fuel.

Naturally occurring peroxidases are important for living organisms and have manifold utility in industries. However, lack of stability in harsh reaction conditions hinders wide applicability of such enzymes. Thus, suitable alternative is vital which can endure severe reaction conditions.

Restructuring thin film composite membrane interfaces using biopolymer as a sustainable alternative to prevent organic fouling.

Replacing polyamide (PA) layer in commercially successful thin film composite (TFC) membranes prepared via interfacial polymerization has been challenging task. Lately, PA is under scrutiny due to its increasing fouling propensity for highly contaminated waters. To mitigate the bio and organic fouling on PA layer in nanofiltration (NF) membranes in a long run, present study attempts to create a new interfacial thin film asymmetric structure using biopolymer chitosan as sustainable alternative.
