Biomedical nanotechnology has witnessed significant progress within the last few decades. Materials at the nanoscale present unique and widely tuneable physicochemical properties that allow numerous unconventional applications to be achieved, which are otherwise not quite possible at larger length scales. More recently, they have found additional usage when combined with other materials at different scales enabling multiscale behaviours that are instrumental for applications that require multiplexed functionalities. This collection focuses on the optical, electrical and magnetic properties of nanomaterials for biomedical applications, the rational design and synthesis of nanomaterials for transdermal drug delivery, biosensing and regenerative medicine, and the use of nanomaterials and their composites for biofabrication.
