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 ...
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. The advantages to the targeted release system is the reduction in the frequency of the dosages taken by the patient, having a more uniform effect of the drug, reduction of drug ...
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 ...
Drug delivery systems have been around for many years, but there are a few recent applications of drug delivery that warrant 1. Drug delivery to the brain: Many drugs can be harmful when administered systemically; the brain is very sensitive to medications and can easily cause damage if a drug is administered directly into the bloodstream.
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 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. This nanocarrier system aims to improve drug stability, control drug release, and improve tumor ...
Nanotechnology is giving rise to nanographene batteries that can store energy more efficiently and weigh less. [26] Lithium-ion batteries have been the primary battery technology in electronics for the last decade, but the current limits in the technology make it difficult to densify batteries due to the potential dangers of heat and explosion ...
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.
