MAGIC BULLET NANOMEDICINES: BRIDGING MOLECULAR TARGETTING AND ADVANCED DRUG DELIVERY TECHNOLOGIES
Abstract
Drug Delivery Systems refer to the science of utilization of technologic advancements and biological polymer materials to deliver drug or gene to the body in clinical time and dose. Targeted drug delivery ensures increased concentration of medication in specific receptors in the body inherently being advantageous with respect to reduction in dose and side effects of drug. This paper discusses about the concept of magic bullet proposed by Paul Ehrlich as well as about the challenges of targeted drug delivery.The various nanocarriers being extensively exploited in targeted delivery are discussed in detail including quantum dots, mesoporous silica materials, metallic nanocarriers, and carbon nanotubes.
