Chromosomal DNA OPTICAL TWEEZERS

Optical tweezers uses light to manipulate microscopic objects as small as single atom.the radiation pressure from a focused laser beam able to trap these smaller particles.in biology these instruments have apply force in PN-range(pico newton) to measure displacement in the nm range of objects ranging in science from 10 nm to over 100nm.optical tweezers instruments will help in all aspects of biology such as to interaction between the cells.optical tweezers have wide applications in various fields especially in aspects of biology.in transported along microutubules,cell manipulation include cell orientation in microscopic analysis,as well as stretching the cells,to diagnose and treat blood clot,red cells in fertility treatment like sperm motility,as molecular motors,studying DNA drug interaction,unzipping the DNA,and to unravel the bacterial chromosomes.

  1. "Optical tweezers uses light to manipulate microscopic objects as small as single atom"

    This is incorrect, microscopic objects are many times bigger (x10,000) than a single atom and optical tweezers are normally used to manipulate objects of at least 1 micron in size.
