Question 3The best description of “bottom up” fabrication is: 1 pointHave a limit of 0.1 microns (100 nm)Building something by assembling smaller componentsStarting with a larger component and carving away material.Utilizing direct writing without a mask on a “resist”

Write a short note on bottom-up approaches for nanomaterial synthesis.

This type of printmaking is done by carving away part of a block to leave a raised surface that can be inked and printed. Group of answer choicessilkscreenreliefmezzotintetchinglithography
