Optical tweezers are specialized scientific tools--particularly useful in biology and medicine--that use high-powered beams of light to trap and manipulate minuscule particles for study. Use of the tool has led to several scientific and medical breakthroughs over the last few decades, but the particles are often under prolonged exposure to the intense heat of the light beams. To overcome the risk of overheating, and thereby damage, researchers sometimes attach nano-sized glass beads to particles, allowing the light to focus on the beads instead of the particles.

Based on the text, what is one advantage of attaching glass beads to particles when using optical tweezers?

Question

Accepted Answer

It facilitates the maneuvering of particles without directly heating the particles themselves.

Answer

It decreases the time it takes for the optical tweezers to locate and capture the particles.

Answer

It allows researchers to use weaker light beams to manipulate particles.

Answer

It adds a material to which particles can transfer any heat absorbed from the optical tweezers' light beam.
