Washington, March 17 : A Purdue University claims to have developed probes that can help pinpoint the location of tumours, and may some day be used to directly attack cancer cells.

Joseph Irudayaraj, an associate professor of Agricultural and Biological Engineering, describes his breakthrough as nanoscale, multifunctional probes that have antibodies on board, to search out and attach to cancer cells.

"If we have a tumour, these probes should have the ability to latch on to it. The probe could carry drugs to target, treat as well as reveal cancer cells," Irudayaraj said.

While previously developed probes use gold nanorods or magnetic particles, Irudayaraj''s nanoprobes use both.
