Tip-specific functionalization of gold nanorods for plasmonic biosensing: effect of linker chain length [PDF]

, 2017
Gold nanorods are promising platforms for label-free biosensing. We have functionalized gold nanorods with biotin thiol linkers of increasing chain length and evaluated their ability in the molecular detection of streptavidin. We have found an unexpected

Soft Hypoxia-Adaptive Bioelectronics Integrating PEDOT:PSS/Polydopamine/Enzyme Biocomposites for Closed-Loop Therapeutics of Chronic Wounds. [PDF]

Adv Sci (Weinh)
Hypoxia‐adaptive bioelectronics based on poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/polydopamine (PDA)/enzyme biocomposites couple O2‐centric biosensing with embedded O2 therapy to address oxygen‐deficient chronic wounds. Local O2 provision restores enzyme‐based metabolite sensing, while catalase‐mediated oxygen generation and

Characterising the biosensing interface

Analytica Chimica Acta, 2022
The development of diagnostic devices relies heavily on the immobilization of biomolecules on supportive substrates, that is the generation of interfaces that can thereafter produce a quantifiable signal upon exposure to a specific target. The ability of a biosensor to selectively recruit analytes is highly dependent on the quality of this receptive ...
