Can nanotechnology be used for cancer treatment?
Cancer therapies are currently limited to chemotherapy,surgery and radiation. All these methods risk damage to normal tissues or leads to incomplete eradication of cancer. Although,there have been many improvements in cancer treatment,cancer is still quite difficult to treat. Chemotherapy can be difficult for a patient to receive.
Medicines are quite strong,and patients undergoing chemotherapy can experience side effects like pain,hair loss,weight loss and tiredness. Suppose we are able to use a special device so that a patient with cancer could get chemotheralc only in cancer cells,without harming his or her healthy cells. Seems to be a good idea rite? This is the goal of researchers who are developing drugs only to the cancer cells.
Nanotechnology provides researchers with the opportunity to study and manipulate macromolecules in real time and during the earliest stages of cancer progression. Nanotechnology can provide rapid and sensitive detection of cancer - related molecules,enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the potential to generate entirely novel and highly effective therapeutic agents.
The use of nanoscale materials for cancer,comes down to it's ability to be readily functionalised and easily tuned,it's ability to deliver or act as the therapeutic,diagnostic,or both,and it's ability to passively accumulate at the tumor site,to be actively targeted to cancer cells,and to be delivered across traditional biological barriers in the body such as dense stromal tissue of the pancreas or the blood - brain barrier that highly regulates the delivery of biomolecules to our central nervous system.

Nano science is very huge and has lot more applications in the field of science . looking at medicine field...it can do wonders. It can also treat at genome level I.e. gene therapy.
ReplyDeleteDefinitely has lot more scope in treating genomic disorders.
Yes very true.. Nanotechnology has multiple applications in the field of science... And the scientists of Israel are also working on curing cancer within a year... Let's hope for the best !
