💥 Check out this awesome post from Hacker News 📖 📂 Category: ✅ Here’s what you’ll learn: LaserTweezer – Optical Trap Optical Tweezers are scientific instruments to manipulate objects of microscopic size. These can be small plastic beads or biological material like cells. The trapping is achieved by focusing a laser beam on the dielectric particles that are then attracted to the region of strongest electric field, which is the center of the beam. The fact that samples under a microscope can be manipulated gives new possibilities to explore. The force applied on the object depends linearly on its displacement…
