Nanomedicine
The application of nanotechnology to medicine and healthcare, enabling precise diagnosis, targeted drug delivery, and molecular-level treatments.
Nanomedicine
Nanomedicine represents the convergence of nanotechnology and medical science, operating at the molecular scale to revolutionize healthcare delivery and treatment approaches.
Core Principles
The fundamental premise of nanomedicine relies on manipulating materials at the nanoscale (1-100 nanometers), where unique physical and chemical properties emerge. This scale is particularly relevant for medical applications as it matches the size of most biological molecules and cellular structures.
