Abstract: This work reports for the first time a colorimetric based biosensor using nanocellulose (NC) based supports drop-deposited onto a cellulose paper substrate for glucose detection in point-of-care. For this purpose, microcrystalline cellulose (MCC) samples were oxidized with 2,2,6,6-tetramethylpiperidine-N-oxyl radical (TEMPO), sodium hypochlorite, and potassium bromide, to produce NC that corresponded to carboxyl- NC. For the characterization, we used several methods: TEM, FTIR and conductometric titration. In all samples, the primary alcohol gr...
