In particular first the different types and properties of paper-based nanobiosensors and nanomaterials are briefly. Aptamer-functionalized nano-biosensors, nanomaterials have become one of the most interesting sensing materials because of their unique size-and shapedependent optical properties, high surface energy and surface-to-volume ratio, and tunable surface properties. Aptamers are oligonucleotides that can bind. LSPR-based nanobiosensors, recent progress in nano-optics has paved the route toward the development of highly sensitive and label-free optical transducers using the localized surface plasmon resonance (LSPR) of metal nanostructures. In this review we describe the basis behind LSPR sensing. Current trends in nanobiosensor technology, the development of tools and processes used to fabricate, measure, and image nanoscale objects has lead to a wide range of work devoted to producing sensors that interact with extremely small numbers (or an extremely small concentration) of analyte molecules.
