Very cool idea of using the dark portion of a beam and still trap. Possible due to high index of refraction of the medium. #opticaltweezers #optics

Hello everybody - here’s my #introduction.

I was a #research #scientist for many years working on #cryobiology, artificial #liver systems, #lasers, #microscopy, and #OpticalTweezers.

I now work as a #grant #funding research development manager. I spend my days reading grant applications and working with hundreds of fantastic #academics in the beautiful town of #StAndrews #Scotland.

I am interested in #sustainability and how we can make the world a better place.
