The peculiar and functional properties of nanostructures and nanocomposites are due to their sizes and shapes in a variety of nanomaterials (i.e., nanoparticles, nanowires, thin films and 2D layers). In recent decades, advanced nanofabrication techniques have enabled applications of nanosized materials in several fields such as sensing devices and nanomedicines. This 2022 article collection highlights promising scientific achievements in nanoscale materials for biomedical/health applications, together with manuscripts on more commonly assessed topics such as sensing and energy storage. Readers can find contributions highlighting the use of nanomaterials for regenerative medicine, cancer therapy and drug delivery together with antibacterial activity and food packaging.
