Nanotechnology has been more prevalent in our daily lives in recent years. Through an integrated approach, this ground-breaking technology has been implemented in a variety of industries. Nanomedicine is the application of nanotechnology for medical reasons, and it is described as the use of nanoparticles for disease diagnosis, monitoring, control, prevention, and therapy. Nanomedicine is the use of nanotechnology to accomplish healthcare innovation. Furthermore, the nanometric scale is also the scale of many biological mechanisms in the human body, allowing nanoparticles and nanomaterials to potentially cross natural barriers to reach new delivery sites and interact with DNA or small proteins at various levels, whether in blood or within organs, tissues, or cells. Hundreds of nanomedicine products are currently in clinical trials, spanning all major diseases such as cardiovascular, neurological, musculoskeletal, and inflammatory diseases. Nanomedicine is an enabling technology in all fields of healthcare, with over 80 marketed products ranging from nano-delivery and pharmaceuticals to medical imaging, diagnostics, and biomaterials.
Nanosensors are sensitive materials that transmit chemical, physical, and biological data regarding nanoparticles and recognition molecules. Nanosensors operate at the "Nano" level. The term "nano" refers to a measuring unit of approximately 109 meters. A nanosensor is a device that can transmit data and information about the behaviour and features of nanoscale particles to a macroscopic level. Nanosensors can be used to detect chemical or mechanical information on the nanoscale, such as the presence of chemical species and nanoparticles, or to monitor physical factors like temperature. The construction and application of nano sensors can be used to classify them.
