Can someone tell me how to speed up a chemical reaction? ?

Increasing temperature speeds up a reaction because there are more collisions and the collisions have higher energy. Catalysts speed up reactions by increasing the number of successful collisions. Catalysts are not used up in a reaction. Smaller particles have a larger surface area.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.
