To combat the threat of chemical and biological warfare agents, there is currently active research on the use of proteins/enzymes as biosensors and as catalysts in remediation textiles.  Protein sensing can result from the enzymatic degradation of analytes to colorful, molecular byproducts.  Ultraviolet-visible spectroscopy can be used to monitor these reactions.  In this study, biologically active membranes were prepared by the electrospinning technique. Nanofiber meshes were spun from aqueous mixtures of poly(vinyl alcohol), protein esterase bovine serine albumin (BSA), and carbon nanotubes (CNTs)- at ~0.25 weight percent of the polymer.  The effects of CNTs and pH of spinning dopes on the topography and activity of BSA fiber mats were investigated.

Topography and enzymatic activity of bovine serine albumin and carbon nanotube incorporated nanofibers
