High-performance modified cellulose paper-based biosensors for medical diagnostics and early cancer screening: A concise review

A remarkable progress in the development of portable paper-based biosensors (PBBs) and microfluidic paperbased analytical devices (μPADs) has recently been achieved. In these devices, a paper formed of microfibers of cellulose, a carbohydrate biopolymer, offers both an ample space in its micropores for analytical reagents storage and a capillary force to drive liquid samples to a dedicated reaction zone for instantaneous detection of the desired analytes. |
