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 ...
Nanoparticles for drug delivery to the brain is a method for transporting drug molecules across the blood–brain barrier (BBB) using nanoparticles.These drugs cross the BBB and deliver pharmaceuticals to the brain for therapeutic treatment of neurological disorders.
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 ...
The most promising drug delivery system is using nanoparticle delivery systems, these are systems where the drug is bound to a nanoparticle capable of traversing the blood–brain barrier. The most promising compound for the nanoparticles is Human Serum Albumin (HSA).
Carvedilol-loaded solid lipid nanoparticles were prepared using hot-homogenization technique for oral delivery with compritol and poloxamer 188 as the lipid and surfactant, respectively. [21] Another example of drug delivery using SLN would be oral solid SLN suspended in distilled water, which was synthesized to trap drugs within the SLN structure.
Another advantage of drug delivery using magnetic nanoparticles is the personability of magnet placement depending on disease state location. [3] While this may also be a limitation, it can be effective if the resources can be used for personally tailored medicine reception.
The high surface area of these nanoparticles allows more drugs to be loaded and encapsulated, leading to higher drug concentrations at the target site. The small size of these particles also encourages cellular uptake, which makes dextran nanoparticles a potential effective drug delivery system for targeting tumor cells. [1]
Another system of drug delivery involving nanoparticles is the use of aquasomes, self-assembled nanoparticles with a nanocrystalline center, a coating made of a polyhydroxyl oligomer, covered in the desired drug, which protects it from dehydration and conformational change.
