Treatments for cancer used until now are not suitable for directing drugs to specific area in a body. Current technique for chemotherapy involves high concentration of drugs to be sent throughout the body to destroy tumor cells. In an effort to destroy cancerous cells using chemotherapy, healthy cells are also destroyed causing discomfort for the patients. Sometimes, destroying healthy cells leads to several side effects for the patients. Because of this reason, many cancer patients prefer to skip chemotherapy. Now, nanoparticles were successfully tested to carry cancer drugs to specific areas. Nanoparticles are made from carefully tested biodegradable polymer. These particles were identified to inhibit the MARK signaling pathway,

present in most of the tumors in human beings. By doing this, nanoparticles suppress the cancer cell multiplication and enable active functioning of chemotherapy drugs. Presently, nanomedicine does not allow efficient drug loading. The polymer used in manufacturing nanoparticles was modified to increase drug loading efficiency by twenty times. Researchers reported that in lab tests using mice, nanoparticles loaded with drugs inhibited growth of cancerous cells and assisted death of such cells. This new research can be used for cancer treatments to target drugs to cancerous tumors, reducing side effects and discomfort for the patients.
