What is nanobiotechnology

for example, nanoparticles can serve as probes, sensors or vehicles for biomolecule delivery in cellular system.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
