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.

One of the issues faced by drug delivery is the solubility of the drug in the body; around 40% of newly detected chemicals found in drug discovery are poorly soluble in water. [28] This low solubility affects the bioavailability of the drug, meaning the rate at which the drug reaches the circulatory system and thus the target site.
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 ...
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 ]
Nanomedicine refers to the use of nanoscale materials for medical applications. In theranostics, nanomedicine offers opportunities for targeted drug delivery, imaging, and therapy. [7] Nanoparticles can be engineered to carry therapeutic payloads, imaging agents, and targeting ligands, allowing for multimodal theranostic approaches. These ...
Drug delivery is a concept heavily integrated with dosage form and route of administration, the latter sometimes being considered part of the definition. [9] While route of administration is often used interchangeably with drug delivery, the two are separate concepts.
Drug delivery is a rapidly growing area that is now taking advantage of nanotube technology. Systems being used currently for drug delivery include dendrimers, polymers, and liposomes, but carbon nanotubes present the opportunity to work with effective structures that have high drug loading capacities and good cell penetration qualities.
Nanoelectronics is a multidisciplinary area composed of quantum physics, device analysis, system integration, and circuit analysis. [13] Since de Broglie wavelength in the semiconductors may be on the order of 100 nm, the quantum effect at this length scale becomes essential. [ 13 ]
