Our recent paper on the functionalization of bacterial cellulose (BC) with metal nanoparticles is published in Advanced Functional Materials:
This work describes a generic strategy for adsorbing well-defined colloidal metal nanoparticles in BC, which render exciting and useful nanocomposite materials. We investigate, among others, a new phenomena that we call “mechanoplasmonic effect”. By compressing the BC composites we can reduce the separation between adsorbed nanoparticles, resulting in dramatic changes in the optical properties of the materials. We show that this effect can be used for sensing proteins, generating heat and improving two-photon absorption.
