Nano-pharmaceuticals offer the ability to detect diseases at much earlier stages and the diagnostic applications could build upon conventional procedures using nano-particles. Nano-pharmaceuticals represent an emerging field where the sizes of the drug particle or a therapeutic delivery system work at the nano-scale. In the pharmaceutical industry, a long standing issue is the difficulty of delivering the appropriate dose of a particular active agent to specific disease site. Nano-pharmaceuticals have enormous potential in addressing this failure of traditional therapeutics which offers site-specific targeting of active agents. Such precision targeting via Nano-pharmaceuticals reduces toxic systemic side effects, resulting in better patient compliance.
