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 ...
Some of the properties that gold nanoparticles possess, such as small size, non-toxicity and non-immunogenicity make these molecules useful candidates for targeted drug delivery systems. With tumor-targeting delivery vectors becoming smaller, the ability to by-pass the natural barriers and obstacles of the body becomes more probable. To ...
The goal of a targeted drug delivery system is to prolong, localize, target and have a protected drug interaction with the diseased tissue. The conventional drug delivery system is the absorption of the drug across a biological membrane, whereas the targeted release system releases the drug in a dosage form.
These devices are faster and more sensitive than typical drug delivery. [15] 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 ...
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 .
Nanocarriers are useful in the drug delivery process because they can deliver drugs to site-specific targets, allowing drugs to be delivered in certain organs or cells but not in others. Site-specificity is a major therapeutic benefit as it prevents drugs from being delivered to the wrong places.
In this drug delivery system, after the drug reaches the target site and tumor cell uptake is complete, an external magnetic field is applied causing a magnetothermal effect, raising the tumor cells' temperature and further promoting drug uptake.
In 2018, the FDA approved Alnylam's siRNA drug Onpattro , the first drug to use LNPs as the drug delivery system. [ 4 ] [ 6 ] By that point in time, siRNA drug developers like Alnylam were already looking at other options for future drugs like chemical conjugate systems , but during the 2010s, the earlier research into using LNPs for siRNA ...
