ABSTRACT
Nanotechnology is the science that deals with processes occurring at molecular and nanoscale levels. Nanotechnology has made considerable progress in physics, electronics and engineering and also emerged as a powerful tool in biomedical, healthcare and pharmaceutical fields including in biophysics, molecular biology, bioengineering, cardiology, oncology, ophthalmology, endocrinology, immunology, etc. Nanotechnology’s current status in the healthcare, pharmaceutical and biomedical sciences includes nanomedicine advancement for drug delivery and formulation development, tissue engineering, nanorobots, biosensors, biomarkers, etc., which are based on some important nanomaterials such as liposomes, nanoparticles, dendrimers, carbon nanotubes, quantum dots, fullerenes, etc. Nanotechnology offers opportunities for improving materials and medical devices and could assist in the development of new technologies where existing and more traditional technologies cannot meet their limits. In brief, recent growth, consumer recognition of various pharmaceutical nanotools and the international interest shown by scientists, governments and industries indicate that nanobased drug delivery systems have enormous potential and will be used for many applications in the near future. Even the scientists working in the field of nanomedicines are advocating the exploration of nanotechnology to fight with COVID-19 pandemic, caused by SARS-CoV-2 virus in late 2019, for promising results.
