Synthesis of a smart gold nano-vehicle for liver specific drug delivery.

ABSTRACT: Targeting drug formulations to specific tissues and releasing the bioactive content in response to a certain stimuli remains a significant challenge in the field of biomedical science. We have developed a nanovehicle that can be used to deliver "drugs" to "specific" tissues. For this, we have simultaneously modified the surface of the nanovehicle with "drugs" and "tissue-specific ligands". The "tissue-specific ligands" will target the nanovehicle to the correct tissue and release the "drug" of interest in response to specific stimuli. We have synthesised a "lactose surface-modified gold nanovehicle" to target liver cells and release the model fluorescent drug (coumarin derivative) in response to the differential glutathione concentration (between blood plasma and liver cells). Lactose is u
