Hoʻohana ʻia kēia pūnaewele e kahi ʻoihana a i ʻole nā ʻoihana a Informa PLC a aia nā kuleana kope āpau me lākou.ʻO ke keʻena i hoʻopaʻa inoa ʻia ʻo Informa PLC ʻo 5 Howick Place, London SW1P 1WG.Kakau ʻia ma ʻEnelani a me Wales.Helu 8860726.
Ua hoʻomohala kahi hui noiʻi ʻo Cal Tech i alakaʻi ʻia e Wei Gao, he polopeka o ka ʻenekinia biomedical, i kahi sensor hiki ke nānā i nā pae o nā metabolites a me nā meaʻai i loko o ke koko o ke kanaka ma ka nānā ʻana i ko lākou hou.ʻO nā mea ʻike wela ma mua ka hapa nui o nā pūhui i ʻike ʻia i nā kiʻekiʻe kiʻekiʻe, e like me nā electrolytes, glucose, a me ka lactate.ʻOi aku ka maʻalahi o kēia mea hou a ʻike i nā pūhui hou i nā haʻahaʻa haʻahaʻa loa.He mea maʻalahi hoʻi ka hana ʻana a hiki ke hana nui ʻia.
ʻO ka pahuhopu o ka hui he mea ʻike e hiki ai i nā kauka ke nānā mau i ke kūlana o nā maʻi me nā maʻi e like me ka maʻi cardiovascular, diabetes, a me ka maʻi maʻi puʻupaʻa, ʻo ia mau mea a pau e hoʻokomo i nā pae kūpono ʻole o nā meaʻai a me nā metabolites i loko o ke kahe koko.ʻOi aku ka maikaʻi o ka poʻe maʻi inā ʻike nui kā lākou kauka i ko lākou kūlana pilikino a pale kēia ʻano i nā hoʻokolohua e koi ai i nā nila a me ke koko.
"ʻO ia mau mea ʻike wela hiki ke hopu wikiwiki, hoʻomau, a noinvasively hoʻololi i ke olakino ma nā pae mole," wahi a Gao."Hiki iā lākou ke hana i ka nānā pono ʻana, ka ʻike mua ʻana, a me ka hana ʻana i ka manawa kūpono.â€
Ke hilinaʻi nei ka mea ʻike i nā microfluidics nāna e hoʻopololei i nā wai liʻiliʻi, maʻamau ma nā kahawai ʻoi aku ka liʻiliʻi o ka hapaha millimeter ka laula.Ua kūpono nā microfluidics no kahi noi no ka mea e hōʻemi lākou i ka mana o ka hoʻoheheʻe ʻana o ka hou a me ka ʻili o ka ʻili i ka pololei o ka sensor.Ke kahe ʻana o ka hou i hoʻolako ʻia ma nā microchannels o ka sensor, e ana pololei ia i ka haku ʻana o ka hou a hopu i nā loli i ka ʻike ʻana i ka manawa.
A hiki i kēia manawa, ʻōlelo ʻo Gao a me kāna mau hoa hana, ʻo ka microfluidic-based wearable sensors i hana ʻia me ka lithography-evaporation approach, e koi ana i nā kaʻina hana paʻakikī a me ka pipiʻi.Ua koho kāna hui e hana i kāna biosensors mai loko mai o ka graphene, he ʻano kalapona e like me ka pepa.Hoʻokumu ʻia nā mea ʻike graphene a me nā kaila microfluidics ma ke kahakaha ʻana i nā pepa plastik me ka laser carbon dioxide, kahi mea maʻamau i loaʻa i nā mea leʻaleʻa home.
Ua hoʻolālā ka hui noiʻi i kāna sensor e ana i ka hanu a me ka puʻuwai puʻuwai, me ka nui o ka uric acid a me ka tyrosine.Ua koho ʻia ʻo Tyrosine no ka mea hiki ke hōʻike i nā maʻi metabolic, maʻi ate, nā maʻi ʻai, a me nā kūlana neuropsychiatric.Ua koho ʻia ka ʻakika uric no ka mea, ma nā pae kiʻekiʻe, pili ia me ka gout, kahi maʻi hui ʻeha e piʻi nui ana ma ka honua.Hoʻomaka ka gout i ka wā e hoʻomaka ai ke kiʻekiʻe o ka ʻakika uric i loko o ke kino i ka crystallizing i loko o nā ami, ʻoi aku ka nui o nā wāwae, e hoʻoulu ai i ka huhū a me ka mumū.
No ka ʻike ʻana i ka maikaʻi o ka hana ʻana o nā mea ʻike, ua hoʻāʻo nā mea noiʻi i nā kānaka olakino a me nā maʻi.No ka nānā ʻana i nā kiʻekiʻe o ka sweat tyrosine i hoʻopili ʻia e ka hoʻoikaika kino kino o ke kanaka, ua hoʻohana lākou i ʻelua pūʻulu o nā kānaka: nā mea haʻuki i hoʻomaʻamaʻa ʻia a me nā poʻe maʻamau.E like me ka mea i manaʻo ʻia, ua hōʻike nā mea ʻike i nā haʻahaʻa haʻahaʻa o ka tyrosine i ka hou o nā mea haʻuki.No ka nānā ʻana i ka pae o ka uric acid, ua nānā ka poʻe noiʻi i ka hou o kahi pūʻulu o nā poʻe olakino e hoʻokē ʻai ana, a ma hope o ka ʻai ʻana o ka poʻe i ka pāʻina nui i nā purines i loko o ka meaʻai i hoʻololi ʻia i ka uric acid.Ua hōʻike ka mea ʻike i ka piʻi ʻana o nā pae uric acid ma hope o ka ʻai.Ua hana ko Gao hui i kahi ho'āʻo like me nā poʻe maʻi gout.Ua hōʻike ka mea ʻike i ko lākou mau pae uric acid i ʻoi aku ka kiʻekiʻe ma mua o ka poʻe olakino.
No ka nānā ʻana i ka pololei o nā mea ʻike, ua huki a nānā nā mea noiʻi i nā laʻana koko mai nā maʻi gout a me nā mea olakino.ʻO nā ana ʻana o nā kiʻekiʻe o ka uric acid i hoʻopili ikaika ʻia me nā pae o ia mea i loko o ko lākou koko.
Ua ʻōlelo ʻo Gao, ʻo ke kiʻekiʻe o ka naʻau, me ka maʻalahi o ka hana ʻana, ʻo ia ka mea hiki ke hoʻohana ʻia e nā poʻe maʻi ma ka home e nānā i nā kūlana e like me ka gout, diabetes, a me nā maʻi cardiovascular.ʻO ka loaʻa ʻana o ka ʻike manawa maoli e pili ana i ko lākou olakino hiki ke ʻae i ka poʻe maʻi e hoʻoponopono i kā lākou pae lāʻau a me ka meaʻai e like me ka mea e pono ai.
