Reports: Scientific novel nano drug, specific killer tumor cells!

Recently, a study in the Journal Reports Dalhousie, researchers at Scientific medical school, developed a new way of delivering chemotherapy drugs. Using nano technology, the new drug delivery system is only in tumor cells to release the drug, thereby protecting healthy cells from damage. The research was published in the Journal Reports Scientific.

Dr. Puvvada Naga, a blogger at New Brunswick Dalhousie (DMNB), invented the drug delivery system. He collaborated with Brunt DMNB, Keith, and researchers in the United States and India to develop the new system.

The team has designed a nano particle that can increase the amount of chemotherapy drugs delivered to the tumor cells, and only release chemotherapy drugs within the tumor cells. This reduces the impact of health organizations to a minimum.

Tumor cells produce a high level of acid, which can activate the nanoparticles, thus allowing them to enter the tumor cells, the release of drugs. When nano particles release the drug, its color will change, that is, the light conversion. This light conversion can help researchers understand how many chemotherapy drugs have been released, and identify the presence of a tumor.

"We design originality is fluorescent light conversion potential clinical possibility of transformation, because it helps to detect chemotherapy drug release. "Dr. Puvvada said. "We will still have a lot of work to do before this technology is used in the clinic because the current fluorescence can't be detected by CTs or MRIs. This is our next step. "

Although the study is carried out on human breast cancer cells, the technology has the potential to be used in any solid tumor.

"Although this new drug delivery system is still in its early stages, it is promising to become a method of individual treatment for patients. "Dr. Brunt, assistant professor of pharmacology. "This target to good, and can detect drug release amount of treatment, there is the potential to improve the quality of life of patients with solid tumors, the overall effect of their just around the corner.
