Biocompatible polymers for skin-integrated bioelectronics: A Mini-Review

Abstract

Many diseasesmanifest themselves through physiological changes in the skin. Themonitoring of disease-associated metabolites in the skin usingbiosensors is a rapidly growing technology that allows the controland diagnosis of diseases almost in real time and with great comfortfor the users. There are currently two major technological trends.Biosensors integrated (tattoo sensors) in the dermis and biosensorsattached to the epidermis (wearable sensors). The contact surfacebetween the biosensors and these skin tissues and fluids is criticalto ensure biocompatibility, sensitivity to the target metabolite,comfort for the user, security and several other features. Ingeneral, the surfaces of the biosensors are made of functionalbiopolymers. This article summarizes the characteristics of thebiopolymers currently used in the construction of skin biosensorsintended for glucose monitoring in sweat.p { margin-bottom: 0.25cm; line-height: 120% }
