Nanopapers-Based Biosensors for Point-of-Care Diagnostics

The emerging demand for low-cost biosensors has resulted in the introduction of non-rigid precursors that are flexible, disposable, biocompatible, and environment friendly. In this context, the nanopaper-based substrate has drawn significant interest among the research community as it has paved a new way to substitute the conventional substrate. In this chapter, we will describe different types of paper that are being used to produce affordable, low-cost biosensing platforms. The modification of the paper substrate with nanomaterials and its various biosensing applications have been discussed. The emerging application of nano paper in point-of-care diagnostics has been highlighted. Furthermore, the challenges and the prospects of these nano paper-based biosensors are summarized.
