Tuning catalytic activity and sensitivity in urease‐based thin film biosensors using conjugated polymers and eugenol/biseugenol

open access: yesPolymer International, EarlyView.
Hybrid thin films of conjugated polymers and urease modified with eugenol derivatives show that polymer–biomolecule interactions enhance catalytic activity while distinctly modulating electrolyte–insulator–semiconductor sensor sensitivity. Abstract Thin films have emerged as promising platforms for biosensor development due to their versatility and ...

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

open access: yesPolymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...
