Researchers develop nanoparticle methods to cure cancer
Prostate cancer researchers from the University of Alberta, Canada, is developing a nanoparticle-based tool to detect and destroy tumors. According to them, nanoparticle method is considered more effective than chemotherapy or other types of treatments.
“For early-stage cancer, this tool can be used to detect tumors. While for later stages, we are developing drugs that specifically kill cancer cells directly,” said researcher John Lewis, as quoted from the Toronto Sun.
Lewis also said that this method could be applied to any type of cancer, not only for prostate cancer patients.
Nanoparticles themselves are included in the nanotechnology that includes the development of technology in the nanometer scale (a nanometer is one millionth of a millimeter).
Meanwhile, head researcher Fong Cho explained that these nanoparticles can be used as a method of detecting simultaneously treat cancer patients.
“Our goal was to develop a method of treatment that targets the cancer cells directly, so it does not harm healthy cells like chemotherapy that had been experienced by patient. Surely nanoparticles have side effects that are relatively smaller than the other methods,” wrote the researchers in the Nano Letters journal.
In addition to developing methods of nanoparticles, the researchers also sought to identify and stop metastasis, the spread of cancer to other parts of the organ. The reason is that these metastases are often the cause of death in patients.
Researchers also confirmed that clinical trials need to be applied to animal experiments before applied to humans.
