Abstract

An optical core-shell microfibrous textile incorporates single-walled carbon nanotubes (SWCNTs) for the real-time optical monitoring of hydrogen peroxide concentrations and other biochemicals in in vitro wounds. The environmentally sensitive and non-photo-bleachable fluorescence of SWCNTs enable continuous analyte monitoring without a decay in signal over time. The microfibrous textiles spatially resolve chemical indicator concentrations using a camera and are integrated into commercial wound bandages without significant degradation in their optical properties.
