Macro photography Challenge - Week 30 | "📷Capture, Click, Compete!📷"

Hello all,

This is my entry to the contest, Macro Photography Challenge - Week 30, organized by @visionaer3003 and sponsored by @visionaer3003.
This is a photo that I took at my laboratory. You can see small nanoparticles called Reduced Graphene Oxide in this image, a famous nanoparticle among scientists.
