Nanotechnology has provided the possibility of delivering drugs to specific cells using nanoparticles. This use of drug delivery systems was first proposed by Gregory Gregoriadis in 1974, who outlined liposomes as a drug delivery system for chemotherapy. The overall drug consumption and side-effects may be lowered significantly by depositing the active pharmaceutical agent in the diseased region only and in no higher dose than needed. Targeted drug delivery is intended to reduce the side effects of drugs in tandem decreases in consumption and treatment expenses. Additionally, targeted drug delivery reduces the side effects of crude or naturally occurring drugs by minimizing undesired exposure to healthy cells. Drug delivery focuses on maximizing bioavailability both at specific places in the body and over a period of time. This can potentially be achieved by molecular targeting by nanoengineered devices. A benefit of using nanoscale for medical technologies is that smaller devices are less invasive and can possibly be implanted inside the body, plus biochemical reaction times are much shorter. These devices are faster and more sensitive than typical drug delivery. The efficacy of drug delivery through nanomedicine is largely based upon: a) efficient encapsulation of the drugs, b) successful delivery of drug to the targeted region of the body, and c) successful release of the drug. Several nano-delivery drugs were on the market by 2019.
