“…In a very recent review, cellulose is considered “a ubiquitous platform for ecofriendly metal nanoparticles preparation” [ 16 ] due to its versatility and efficiency to incorporate a wide range of metallic and metal oxide nanoparticles. Often, to impart a broader area of applicative domains, cellulose derivatives, including those carrying carboxyl groups as for example TEMPO-oxidized cellulosic materials in form of powder, fibers and films are prepared [ 17 , 18 , 19 , 20 ]. In this way, the newly introduced functionalities improve specific properties such as solubility in organic solvents and processability, also creating dedicated sites for anchoring various (bio)organic carriers.…”
