The criteria for an ideal drug carrier include maximum effect upon delivery of the drug to the target organ, evasion of the immune system of the body in the process of reaching the organ, retention of the therapeutic molecules from preparatory stages to the final delivery of the drug, and proper release of the drug for exertion of the intended ...
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.
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.
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 ...
[1] [2] Once synthesized, the capsules can enclose drugs, [6] quantum dots, [1] and other nanoparticles, to list a few examples. Further fine-tuning of the chemical and topological properties of these polymer capsules could prove an effective route to create drug-delivery systems. [1] [6]
Nanofabrics research is an interdisciplinary effort involving bioengineering, [5] molecular chemistry, physics, electrical engineering, computer science, and systems engineering. [3] Applications of nanofabrics have the potential to revolutionize textile manufacturing [6] and areas of medicine such as drug delivery and tissue engineering. [7]
A drug carrier or drug vehicle is a substrate used in the process of drug delivery which serves to improve the selectivity, effectiveness, and/or safety of drug administration. [1] Drug carriers are primarily used to control the release of drugs into systemic circulation.
A composite Taylor cone formulates at the orifice of the needle encompassing the two solutions, fed to the needle from two independent reservoirs (syringe pumps). In this example, a negatively charged mandrel is used as a collector. The positively charged core/shell nanofibers expand and solidify as they advance towards the collector's surface.
