SCOBY is a biomaterial derived from a symbiotic culture of bacteria and yeast. Its structure is characterized by intercalated nanocellulose fibers. There has been increased interest in using this bacterial nanocellulose to medical applications and in biosensors. For successful applications, their mechanical, optical, and electrical properties need to be characterized and improved. We report experimental results on the optical absorption, emission, and scattering properties of SCOBY and derivations of SCOBY. In addition, we demonstrate improved electrical conductivity by the addition of PEDOT:PSS and AgNPs into the nanocellulose matrix, leading to the possibility of SERS and luminescence emission for nanoscale biosensing applications.
