ʻO nā nanoparticles gula he hoʻokuʻu ʻia me ke gula nui nano i hoʻokuʻu ʻia i loko o kahi mea hoʻoheheʻe, ka wai pinepine.Loaʻa iā lākou nā waiwai optical, uila, a me ka wela a hoʻohana ʻia i kahi ākea o nā noi e like me diagnostics (lateral flow assays), microscopy and electronics.

ʻO ka Nano-gula e pili ana i nā ʻāpana liʻiliʻi o ke gula me ke anawaena o 1-100 nm.He kiʻekiʻe electron density, dielectric waiwai a me ka catalytic hopena.Hiki ke hoʻohui ʻia me nā macromolecules olaola like ʻole me ka hoʻopilikia ʻole ʻana i kāna hana olaola.ʻO nā waihoʻoluʻu like ʻole o ka nano-gula he ʻulaʻula a i ka poni ma muli o ka ʻike.

No nā mea noi nanoparticles, e hoʻopuehu maikaʻi iā lākou he mea paʻakikī ia no nā mea hoʻohana ʻole, e hāʻawi i ka nano Au colloidal / dispersion / wai e maʻalahi a maʻalahi no ka hoʻohana pololei.
