This study focuses on the fabrication of a novel, flexible and disposable textile based biosensing platform by the use of an absorbent microfibrous nonwoven substrate as the base material. This platform was fabricated via photolithography technique. Physical barriers were designed using a hydrophobic photo-resist polymer which defined the liquid penetration pathways on the fabric surface. The potential of the system was tested by constructing an enzyme biosensor based on colorimetric detection of lactic acid and hydrogen peroxide. This bio-sensing platform may be used for the rapid detection of various kinds of analytes such as glucose, lactic acid and uric acid.
