Nanomedicine seeks to deliver a valuable set of research tools and clinically useful devices in the near future. [ 4 ] [ 5 ] The National Nanotechnology Initiative expects new commercial applications in the pharmaceutical industry that may include advanced drug delivery systems, new therapies, and in vivo imaging.

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 ...
Coating these polymeric nanoparticle devices with different surfactants can also aid BBB crossing and uptake in the brain. Surfactants such as polysorbate 80, 20, 40, 60, and poloxamer 188, demonstrated positive drug delivery through the blood–brain barrier, whereas other surfactants did not yield the same results. [ 2 ]
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 ...
Nanocarriers range from sizes of diameter 1–1000 nm, [3] [4] however due to the width of microcapillaries being 200 nm, nanomedicine often refers to devices <200 nm. [4] Because of their small size, nanocarriers can deliver drugs to otherwise inaccessible sites around the body.
The device with single-walled CNTs showed a sensitivity higher than that of multi walled CNTs. The glucose biosensor showed ultrasensitivity (a sensitivity of 40 μA mM-1 cm-2, a correlation coefficient of 0.992, a linear response range of 0.025 –1.9 mM, a detection limit of 6.2 μM at S/N = 3, +0.8V vs Ag/AgCl), and a rapid response (<4 ...
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.
Transfersome is a proprietary drug delivery technology, an artificial vesicle designed to exhibit the characteristics of a cell vesicle suitable for controlled and potentially targeted drug delivery. Some evidence has shown efficacy for its use for drug delivery without causing skin irritation, [1] potentially being used to treat skin cancer. [2]
