Cancer is usually treated with a number of chemotherapeutic agents but the results and outcomes are not 100%. But now a new shine have reached us giving a promise to our next generation about 100% and perfect cure of cancer. Pharmaceutical engineers developed a new technology to treat the cancer with a great precision. This new technology is the use of NANODIAMONDS having a coat of the drug and proteins that targets the Caner cell in body and destroy the cancerous cells without affecting any normal cell.

Nanodiamonds are the diamond crystals less than 100 thousands million of meter in size. Delivery of drug using this system reduces the side-effects and improves the targets. Using nanodiamonds, researchers at the McCormick School of Engineering and Applied Science have demonstrated a new tool designed to precisely deliver tiny doses of drug-carrying to individual cells – the Nanofountain Probe.

The team led by Prof. Horacio Espinosa and Assist. Prof. Dean Ho have shown that these nanomaterials can shuttle chemotherapy drugs to cells without producing the negative effects of today’s delivery agents. Clusters of the nanodiamonds surround the drugs to ensure that they remain separated from healthy cells until they reach the cancer cells, where they are released. Further good news is that these nanodiamonds have been shown not to induce inflammation in cells once they’ve done their job.

The Nanofountain Probe use to deliver the drug-coated nanodiamonds and acts in two ways:

First it the nanodiamonds act as the ink for the pen, Secondly these nanodiamonds are injected into the circulation. The group used the Nanofountain Probe to injected tiny doses of nanodiamonds into both healthy and cancerous cells.

In previous work Ho and his colleagues developed a patch to deliver chemotherapy drugs locally to sites where cancerous tumors have been removed. The patch is embedded with a layer of drug-coated nanodiamonds, which moderate the release of the drug over a period of months, reducing the need for chemotherapy following the removal of a tumor. “An attractive enhancement will be to use the Nanofountain Probe to replace the continuous drug-nanodiamonds films.

Another aspect of the work being conducted by the group is the delivery of a wide variety of bio-agents, including DNA, viruses and other therapeutically relevant materials. The work was supported by the National Science Foundation, the National Institutes of Health, The V Foundation for Cancer Research and the Wallace H. Coulter Foundation and the results were recently published online in the scientific journals.

Nanodiamonds drug delivery system shows a new path to the medical science. This technology reveals many roads toward the effective and safe treatment of Cancer. Researches are continuing on this topic. We all hope that one day the cancer will not a fatal or a complicated disease for us.
