Nanochemistry and nanomedicine have emerged as pivotal interdisciplinary fields that explore and exploit matter at the nanoscale to address fundamental scientific challenges and practical applications, particularly in healthcare. Originating from early conceptual foundations proposed by Richard P. Feynman and later enabled by advances in nanotechnology and analytical tools, nanochemistry focuses on the controlled synthesis, characterization and functionalization of nanomaterials. These developments have led to the discovery of novel nanostructures such as nanoparticles, carbon nanotubes, nanoshells, quantum dots and two-dimensional materials with unique optical, electronic and catalytic properties. The convergence of nanochemistry with medicine has given rise to nanomedicine, which aims to improve drug delivery, diagnostic imaging and therapeutic efficacy while minimizing toxicity and enhancing target specificity. Despite remarkable progress and promising applications, challenges related to biocompatibility, toxicity, pharmacokinetics and regulatory validation remain significant. Continued interdisciplinary research and sustainable design strategies are essential for the safe and effective translation of nanochemical innovations into clinical and industrial practice.
