What is acid by Lewis in science​

Included in the Lewis definition of acids are the metal ions; the oxides of certain nonmetallic elements, such as sulfur, phosphorus, and nitrogen; substances able to donate hydrogen ions or protons; and certain solid compounds, such as aluminum chloride, boron trifluoride, silica, and alumina. ;)

A Lewis acid is a substance that accepts a pair of electrons to form a covalent bond. A Lewis base is a substance that donates a pair of electrons to form a covalent bond. So, a Lewis acid-base reaction is represented by the transfer of a pair of electrons from a base to an acid.

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.
