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 ...
For example, drug-conjugated silver nanoparticles are created by reducing silver nitrate with sodium borohydride in the presence of an ionic drug compound. The drug binds to the surface of the silver, stabilizing the nanoparticles and preventing the nanoparticles from aggregation.
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 ...
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 ]
Solid lipid nanoparticles can function as the basis for oral and parenteral drug delivery systems. SLNs combine the advantages of lipid emulsion and polymeric nanoparticle systems while overcoming the temporal and in vivo stability issues that troubles the conventional as well as polymeric nanoparticles drug delivery approaches.

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.
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] Exosomes and dendrimers are other potential nanocarriers.
