<prompt> Fingqa isihloko: Ukudla okunobuthi kuthinta umuntu oyedwa kwabayisithupha baseMelika unyaka ngamunye okubangelwa inyama nemifino ebolile, amanzi angcolile namakhishi angahlanzekile. Kodwa indlela entsha esebenzisa ugesi namanzi kuphela ngelinye ilanga ingenza ukudla kuphephe kakhudlwana, ngaphandle kokulimaza imvelo. Abacwaningi bathi amaconsi amancane anjengama-nanometer amanzi agcwele amandla kagesi agcwele ama-radical amahhala angagcotshwa ekudleni ukuze kubulawe amagciwane agcwele ekudleni. Ososayensi baseHarvard University eCambridge, eMassachusetts bakholelwa ukuthi uma kwenziwa ucwaningo olwengeziwe, amaconsi abizwa ngokuthi ama-Engineered Water Nanostructures EWNS angase athathe indawo yezindlela ezisetshenziswayo njengamanje zokubulala amagciwane ekudleni, njengokusebenzisa izixazululo ezincane ze-bleaches ne-chlorine. Ososayensi babhala kulolu cwaningo lwabo olwanyatheliswa kuyi-Environmental Science and Technology. Bathi: Izithelo nemifino kungangcoliswa amagciwane ayingozi noma kuphi lapho kukhiqizwa khona, kusukela ensimini noma esivandeni, lapho kuvunwa, kuthuthwa, kusetshenzwa, kusatshalaliswa futhi kuthengiswa, noma lapho kulungiswa ezindaweni zokudla nasekhaya. Imithombo ye-pathogen engaba khona ihlanganisa amanzi angcolisiwe okunisela, izilwane, izinyoni, izinambuzane, inhlabathi, umquba, kanye nabasebenziabasebenza ngokudla abanegciwane. Kuye ngokuthi izithelo nemifino kwachithwa isikhathi eside kangakanani, ukuhlolwa kwaselabhorethri kwabonisa ukuthi amaphesenti angu-80 kuya kwangu-98 amabhaktheriya ayebhujisiwe. Kuboniswa isithombe se-SEM se-E. coli. Uma ucabanga ngokudliwa ukudla okunobuthi ungase ucabange ukuthi inyama eluhlaza iyona imbangela. Kodwa izithelo nemifino eluhlaza noma ecutshungulwe kancane kungaba umthombo wamagciwane abangela izifo, njengamagciwane, amagciwane, nezinambuzane, kusho lolu cwaningo. Unyaka ngamunye e - US, abantu abangaba yizigidi ezingu - 48 bayagula, abangu - 128 000 bayiswa esibhedlela, futhi abangu - 3 000 babulawa izifo ezidluliselwa ukudla. Phakathi kuka-1990 no-2005,...  <response>: Ochwepheshe bakha amaconsi besebenzisa amanzi anegesi kanye nama-radicals amahhala. Uma zifafazwa ezithelweni nemifino, zingabulala amabhaktheriya afinyelela kuma-98. I-E. coli, i-Salmonella ne-Listeria kwahlolwa ekuhlolweni kwamatamatisi. Le ndlela ingase ngelinye ilanga ithathe indawo yezindlela zamanje zokubulala amagciwane ekudleni.
