Advance Engineered Nanomaterials in Point-of-care Immunosensing for Biomedical Diagnostics

In the last few years, immunosensors have become critical research endeavours in research studies across the globe. Scientists worldwide are focusing on harnessing the exceptional atomic and molecular properties of engineered nanomaterials and their composites for better biological applications. Engineering nanomaterials to develop multiple functionalities into a single or combined nanoscale entity can pave the way towards a new aspect in the realm of modern immunosensors. The significant role of these materials in nano-biotechnology is going to be evident in the journey of this revolution in the scope of bio-interfacing and the fabrication of efficient detection probes. There is a need to document the relevant and exciting methodologies used in developing engineered functional nanomaterials and their possible applications in the discipline of biomedical engineering. Realising the fact that the journey of nanomaterials and their composites in the biomedical diagnostic area is going to attract the interest of readers of interdisciplinary intellectual space, we aim to encompass in the content of this chapter almost every important aspect of nanomaterials in the biomedical area starting from synthesis, characterisation, design, functionalisation, and bio-interfacing to the use of nanomaterials in designing efficient diagnostic platforms. We will also include an explanation of the substantial role of engineered nanomaterials in miniaturisation of the technology and the effect on the commercial aspects of biosensors. This chapter will also provide the vision of future prospects of engineered nanomaterials in advanced futuristic biosensors.
