Ndị na-eme nchọpụta na Mahadum Central Florida ewepụtala ọgwụ na-efe efe nke nanoparticle nwere ike na-egbu nje virus n'elu ruo ụbọchị asaa - nchọpụta nke nwere ike bụrụ ngwa ọgụ siri ike megide COVID-19 na nje nje ndị ọzọ na-apụta.
E bipụtara nyocha a n'izu a na akwụkwọ akụkọ ACS Nano nke American Chemical Society site na otu ìgwè nke nje virus na ndị ọkachamara injinịa sitere na mahadum na onye isi ụlọ ọrụ nkà na ụzụ na Orlando.
N'oge mmalite nke ọrịa a, Christina Drake, onye UCF alumnus na onye guzobere Kismet Teknụzụ, sitere n'ike mmụọ nsọ ka ọ gachara n'ụlọ ahịa ihe nri iji mepụta ọgwụ na-efe efe. N'ebe ahụ, ọ hụrụ otu onye ọrụ ka ọ na-efesa ọgwụ na-edozi ahụ n'aka friji ma hichapụ ya ozugbo.
Ọ sịrị, "Na mbụ echiche m bụ ịmepụta ọgwụ na-eme ngwa ngwa," ka o kwuru, "ma anyị na ndị na-azụ ahịa kwurịtara - dị ka ndị dọkịta na ndị dọkịta ezé - iji chọpụta ọgwụ nje ha chọrọ n'ezie.

Drake jikọrọ aka na Dr. Sudipta Seal, onye injinia akụrụngwa UCF na ọkachamara nanoscience, na Dr. Griff Parks, ọkà mmụta banyere ọrịa virologist, onye otu onye nyocha nke School of Medicine, na Dean nke Burnett School of Biomedical Sciences. Site na ego sitere na National Science Foundation, Kismet Tech, na Florida High-Tech Corridor, ndị ọrụ nyocha mepụtara ọgwụ nje nanoparticle mebere.

“Ọ na-arụ ma na kemistri ma ígwè ọrụ,” ka Seal na-akọwa, bụ́ onye nọworo na-amụ nanotechnology ihe karịrị afọ 20. “Nanoparticles na-ebunye eletrọn iji mee ka nje ahụ oxidize ma mee ka ọ ghara ịrụ ọrụ. N'iji arụ ọrụ, ha na-etinyekwa onwe ha na nje a wee gbawaa elu dị ka balloon na-agbawa agbawa. "
