Gold and Lasers Produce Plasmonic Na**bubbles to Kill Residual Cancer Cells

A team of scientists*headed by folks at Rice University have developed a way of killing off neoplastic*cells that often remain after surgical procedures and end up causing a recurrence of cancers. The investigators managed to produce gold na**particles with cancer antibodies attached to them that seek out specific cancer cells. The gold na**particles are sensitive to laser light, quickly heating up and producing a so-called plasmonic na**bubble*within surrounding liquid. This destroys the cancer cell to which the antibody was attracted, but it also pinpoints the location where the killing occurred.
The tech**logy could be used to both help surgeons target cancer tumors with a few laser bursts, removing most of the offending tissue the old-fashioned way, and following up with a more thorough plasmonic na**bubble attack to sweep up the remains.
Here’s a short video showing a cancer cell explode from a plasmonic na**bubble attack:
