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 ...
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. [1] [5] Most polymers ...
Drug delivery systems, lipid-[18] or polymer-based nanoparticles, can be designed to improve the pharmacokinetics and biodistribution of the drug. [ 19 ] [ 20 ] [ 21 ] However, the pharmacokinetics and pharmacodynamics of nanomedicine is highly variable among different patients. [ 22 ]
UCNP-based systems can couple both light-based techniques and current-based techniques. This optical stimulation of semiconductors is then coupled with voltage-based stimulation in order to store information. [72] Other advantages of utilizing UCNPs for flash drives include that all materials employed are photo- and thermally stable.
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.
Nanoparticles are drug delivery systems ranging from 1–1000 nm in diameter. Lipid-based and polymer-based nanocarriers are commonly used for nose-to-brain delivery as they exert high stability, solubility, and adherence. [ 36 ]
Magnetic nanoparticle drug delivery is the use of external or internal magnets to increase the accumulation of therapeutic elements contained in nanoparticles to fight pathologies in specific parts of the body.
