Some the pharmaceutical company where companies are looking

Some of the goals of bio-nanotechnology is being able to construct particles that can specifically target and destroy cancer (like small bombs that detonate only at their target)It’s a growing sector of research, but will not be applied to the commercial market in awhile.It exploits that behavior of the properties of materials on the nanoscale (10^-9 m)The benefits of nanotech include enhanced drug solubility and the ability of particles to enter cells, cross membranes, and cross the blood-brain barrier, but if they are uncontrolled, they can pose a great threat. Also, the effect of the technology on humans is not available yet.New particle called fullerenes used as a potent antioxidantNanoshells can be tuned to absorb or reflect different light waves, which can be used to target cancer cells and tumors.It can also help in the pharmaceutical company where companies are looking for different ways to encapsulate drugs to minimize side effects and increase solubility and bioavailability. the dendrimer hollow interior, using a surface-bound targeting molecule to direct the complex to its intended target. Another dendrimer company, NanoCure, covalently attaches drug molecules to the dendrimer surface along with a targeting moietyAnother way bionanotech can be used is in tissue regeneration with the development of self-assembling liquids that solidify upon injection. This tissue then forms structured scaffolds that present peptides to cells.The particles can present a risk to human health is abused. Dendrimers can cause osmotic damage, activate the clotting and complement systems, and rip cell membranes off. Another nanodevelopment called quantum dots are made of metals and if the medals were to leak out, they would be toxic to the consumer.Quantum dots can be used to locate tumors. Example: Surveys conducted show that many people are not familiar with nanotechnology, but many believe it will change the world for the better.Vollick, E. (2014, Jan. 27). DNA-built Nanoparticles Safely Target Cancer Tumours. University of Toronto. Retrieved from article was about a recent development of nanoparticles that safely targeted cancer cells. They consisted of gold nanoparticle blocks that carried cancer medicine into the tumor. The blocks were “glued” by DNA which allowed them to stay in the tumor. The feat of getting medicine into the tumor and staying there was an accomplishment because beforehand, the particles would be so small that they would pass through quickly, or so large that they would not be able to get in. One disadvantage is that these particles of metal might cause risks for other long term problems in the future.Merkle, R. (2000, Apr.). Nanotechnology: It’s a Small, Small, Small, Small World.

Solar cells would be easier to produce, making them less costly and more available.MedicalHeal injuries at the cellular and atomic level Dreher, K. L. (2004).
