This means of delivery is largely founded on nanomedicine, which plans to employ nanoparticle-mediated drug delivery in order to combat the downfalls of conventional drug delivery. These nanoparticles would be loaded with drugs and targeted to specific parts of the body where there is solely diseased tissue, thereby avoiding interaction with ...
pH-responsive tumor-targeted drug delivery detects the changes in the pH within the body. These polymer drug carriers carry the therapeutic drugs to allow for targeted drug delivery. The purpose of the pH- triggered drug release is to deliver the drug precisely to the area of the tumor and not activate and release the drug in healthy tissue. [1]
Nanoparticle drug delivery systems are engineered technologies that use nanoparticles for the targeted delivery and controlled release of therapeutic agents. The modern form of a drug delivery system should minimize side-effects and reduce both dosage and dosage frequency. Recently, nanoparticles have aroused attention due to their potential ...
A modified nanoparticle with siRNA is now being researched and has been shown to effectively shut down the expression of gro-α. They are modified with FSH β which has a high selectivity for FSHR-positive ovarian cancer cells. The nanoparticles are aiding in delivery of the siRNA to the correct place, giving them a high selective toxicity. [2]
Other potential applications of magnetic nanoparticles are brain imaging and drug delivery past the blood-brain barrier (BBB) using biodegradable magnetic iron oxide nanoparticles. The scope of this application is the treatment of central nervous system (CNS) disorders by functioning as contrast agents and drug carriers.
This was a huge breakthrough in the nanoparticle drug delivery field, and it helped advance research and development toward clinical trials of nanoparticle delivery systems. Nanoparticles range in size from 10 - 1000 nm (or 1 μm) and they can be made from natural or artificial polymers , lipids , dendrimers , and micelles .
In photothermal cancer therapy, many gold nanoparticle molecules are used in each test and they must all be uniform in size. Including PEG coating, the nanoparticles measured to be ~130 nm in diameter. [1] Gold nanoparticles that act as drug delivery systems in conjugation with chemotherapeutic drugs typically range in size from 10 to 100 nm. [2]
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. [16] Several nano-delivery drugs were on the market by 2019. [17]
