ʻO ka polystyrene, hoʻohana pinepine ʻia e hana i ka ʻūhā i hoʻonui ʻia, ua kūpono hoʻi i ka hana ʻana i nā latex, kahi e hoʻokuʻu ʻia ai nā ʻāpana polystyrene liʻiliʻi liʻiliʻi.Hoʻohana ʻia lākou i ka hana ʻana i nā uhi a me nā pena a no nā kumu calibration i ka microscopy a me kakiʻi lāʻau lapaʻaua me ka noiʻi biology cell.Hana ʻia lākou e ka thermally a i ʻole redox-inducedpolymerizationi loko o ka hoʻonā.
No ka loaʻa ʻana o ka mana o waho ma luna o ke kaʻina hana, ua huli nā hui ʻo Muriel Lansalot, Emmanuel Lacôte, a me Elodie Bourgeat-Lami ma ka Université Lyon 1, Farani, a me nā hoa hana i nā kaʻina hana māmā."Hōʻike ka polymerization māmā i ka mana kino, no ka mea, hele wale ka polymerization i mua o ka mālamalama, akā hiki ke hoʻomaka ʻia nā ʻano wela akā ʻaʻole i hoʻōki i ka wā e hoʻomaka ai," wahi a Lacôte.
ʻOiai ua hoʻokumu ʻia nā ʻōnaehana photopolymerization e pili ana i ka UV- a i ʻole nā blue-light, he mau palena.Hoʻopuehu ʻia ka pāhawewe lōʻihi pōkole i ka wā o kanui ʻāpanae pili ana i ka lōʻihi hawewe radiation, e hana ana i nā latex me ka nui o nā ʻāpana ʻoi aku ka paʻakikī o ka hana ʻana.Eia kekahi, ʻoi aku ka ikaika o ke kukui UV, ʻaʻole e haʻi i ka pōʻino i nā kānaka e hana pū ana me ia.
No laila ua hoʻomohala ka poʻe noiʻi i kahi ʻōnaehana hoʻomaka kemika maikaʻi e pane i ke kukui LED maʻamau i ka laulā ʻike.ʻO kēia ʻōnaehana polymerization, ka mea i hoʻokumu ʻia ma ka acridine dye, stabilizers, a me kahi pūhui borane, ʻo ia ka mea mua i lanakila ma luna o ka "300-nanometer ceiling," ka palena nui o ka polymerization UV a me ka blue-light-driven polymerization i loko o kahi medium dispersed.ʻO ka hopena, no ka manawa mua, ua hiki i ka hui ke hoʻohana i ka māmā no ka hana ʻana i nā polystyrene latex me ka nui o nā ʻāpana i ʻoi aku ma mua o hoʻokahi micrometer a me nā anawaena kūlike loa.
