The present review highlights the development and relevance of various advanced nanocarrier systems in the field of nanomedicine for delivering drugs, contrast agents and antibodies to different sites in the body. Wherever appropriate, emphasis on targeting to tumor site is discussed to support the concepts. Several multifunctional nanoparticles developed recently and possessing unique characteristics are also discussed. The scientific contributions, technological gaps and promising opportunities presented by advanced and sophisticated but hypothetical nanodevices of future, known as ‘medical nanorobots’ are also described that are designed for superior targeting efficiency, controlled drug release, optimum dosing and wide range of other functional capabilities.
