Title:
ULTRALOCALIZED OPTICAL HEATING METHOD AND DEVICE FOR CARRYING OUT SAME
Document Type and Number:
WIPO Patent Application WO/2023/153960
Kind Code:
A1
Abstract:
The invention relates to the field of nanotechnology, more particularly to exerting an utralocalized thermal effect on an object under examination, and even more particularly to controlled heating using a nanodiamond heater. The present ultralocalized optical heating method is based on exposing to laser radiation nanoparticles fixed in the end of a glass capillary that is placed in a medium under examination. An ultralocalized optical heating device for carrying out this method comprises a nanoparticle disposed in a glass capillary that is mounted in a micromanipulator, wherein the nanoparticle is disposed in the end of the glass capillary and is a polycrystalline diamond particle containing amorphous carbon at its grain boundaries, which is optically coupled to a source of laser radiation and to a luminescence recording unit, wherein the diamond particle contains at least one luminescent impurity centre and the glass capillary is placed in a medium under examination.
