Light

Halina Rubinsztein-Dunlop explains how quantum light can make tiny tractor-beams to move and wiggle things.

Halina is widely recognised for her substantial achievements in moving things with light. "Optical tweezers" are tiny tractor beams that can move and wiggle small particles (larger objects are "safe" because they'd probably burn up before being lifted off a planet into alien spaceships for example). This technique has an enormous number of applications such as wiggling the balance system of zebra fish to study how signals move through brain neurons, and heating gold nanoparticles to burn cancer cells from the inside. Halina was the first female full professor of physics in Australia, and we applaud her active (and ongoing) work to promote and achieve diversity in science.
