We report a straightforward aqueous synthesis of black gold nanoassemblies based on supramolecular guanosine quartet (G4) assembly and a dextran co-matrix, in which the functional photothermal component is an interconnected Au(0) plasmonic network. Dextran acts as a multifunctional polymeric co-matrix that helps organize the guanosine moieties and subsequently influences the nucleation and growth…

Using agro-industrial residues with effective technologies is key to advancing a circular bioeconomy. This study proposes the use of phenolic compounds extracted from cashew apple bagasse for green technology applications (subcritical water) and their incorporation into wheat starch cryogel. The cryogels were extensively characterized in terms of morphology, physical-chemical, mechanical, thermal…

Biological lubricants are essential for the effective functioning of biomedical systems that involve relative motion. Hyaluronic acid (HA) is often used for its excellent lubrication properties; however, its long-term effectiveness is compromised by its tendency to accelerate metal corrosion. Incorporating cellulose nanocrystals (CNCs) into HA offers a promising solution due to CNCs' corrosion-in…

Fluorescent protein (FP) variants have recently emerged as promising intracellular nitric oxide (NO) sensors based on NO-induced fluorescence loss due to cysteine S-nitrosylation - the covalent addition of a nitroso group to a cysteine thiol within a protein to form an S-nitrosothiol. Here, we investigate the mechanisms underlying this fluorescence loss using a combined experimental and computati…
