Graphene "mea kilokilo"

Hiki ke hoʻohana ʻia ka graphene "mea kilokilo" no ka ʻike wikiwiki a pololei hoʻi o COVID-19
Wahi a nā hōʻike pāpāho haole, ua hoʻohana pono nā kānaka noiʻi ma ke Kulanui o Illinois ma Chicago i ka graphene, kekahi o nā mea ikaika loa a lahilahi loa i ʻike ʻia, e ʻike i ka maʻi sars-cov-2 i nā hoʻokolohua hale hana. Hiki i nā ʻike ke lilo i holomua i ka ʻike ʻana iā COVID-19 a hiki ke hoʻohana ʻia i ke kaua kūʻē iā COVID-19 a me kona ʻano like ʻole, wahi a nā kānaka noiʻi.
I ka hoʻokolohua, ua hui pū nā mea noiʻinā pepa grapheneme ka mānoanoa o 1/1000 mau sila wale nō me kahi antibody i hoʻolālā ʻia e kuhikuhi i nā glycoproteins kaulana ma COVID-19. A laila ua ana lākou i nā haʻalulu pae atomika o nā pepa graphene i ka wā i hōʻike ʻia ai lākou i nā laʻana cowid maikaʻi a me cowid maikaʻi ʻole i loko o ka lawai hana. Ua loli ka haʻalulu o ka pepa graphene i hoʻopili ʻia me ka antibody i ka wā i mālama ʻia ai me nā laʻana maikaʻi o cowid-19, akā ʻaʻole i loli i ka wā i mālama ʻia ai me nā laʻana maikaʻi ʻole o cowid-19 a i ʻole nā ​​​​coronavirus ʻē aʻe. ʻIke maopopo ʻia nā loli haʻalulu i ana ʻia me kahi mea i kapa ʻia ʻo Raman spectrometer i loko o ʻelima mau minuke. Ua paʻi ʻia kā lākou mau ʻike ma ACS Nano ma Iune 15, 2021.
"Pono maopopo i ke kaiāulu nā ʻano hana ʻoi aku ka maikaʻi e ʻike koke a pololei i ka covid a me kona mau ʻano like ʻole, a he hiki i kēia haʻawina ke lawe mai i ka loli maoli. Loaʻa i ka sensor i hoʻomaikaʻi ʻia ke kiʻekiʻe o ka ʻike a me ke koho ʻana i ka covid, a he wikiwiki a haʻahaʻa ke kumukūʻai," wahi a Vikas berry, ka mea kākau kiʻekiʻe o ka pepa "Thenā waiwai kū hoʻokahiʻO ka hana a ka graphene "mea kilokilo" e hoʻolilo iā ia i mea maʻalahi loa, kahi e hiki ai ke hana i kēia ʻano sensor.
He ʻano mea hou ʻo Graphene me nā ʻātoma kalapona i hoʻopili ʻia me ka hybrid SP2 i hoʻopaʻa paʻa ʻia i loko o kahi ʻano honeycomb lattice hoʻokahi papa ʻelua-dimensional. Hoʻopaʻa ʻia nā ʻātoma kalapona e nā pilina kemika, a hiki i ko lākou elasticity a me ka neʻe ʻana ke hana i ka haʻalulu resonance, i ʻike ʻia hoʻi ʻo phonon, hiki ke ana pololei ʻia. Ke launa pū kahi molekala e like me sars-cov-2 me graphene, hoʻololi ia i kēia mau haʻalulu resonance ma ke ʻano kikoʻī loa a hiki ke helu ʻia. ʻO nā noi hiki o nā sensor unahi atomika graphene - mai ka ʻike ʻana i ka covid a i ka ALS a i ke kanesa - e hoʻomau i ka hoʻonui ʻia, wahi a nā mea noiʻi.
