Nanotechnology ke lekala la saense le ntseng le hola ka potlako le tšepisang ho fetola masimo a kang bongaka, theknoloji ea tlhahisoleseling, matla le tikoloho. Poleloana "nanotechnology" e bolela ho laola lintho ka tekanyo ea nanometer, karolo ea limilione tse likete ea mithara, e lumellang bo-rasaense ho theha le ho laola meaho ka ho nepahala ho makatsang. Sengoloa sena se tla hlalosa tlhaloso ea nanotechnology, melao-motheo ea eona ea motheo, le melemo e fapaneng eo e fanang ka eona.
Ho utloisisa theknoloji ea Nanotechnology
Nanotechnology e hlalosoa e le thuto le ts'ebeliso ea lintho tse nyane haholo, sekaleng sa nanometer. Ho beha sena ka nepo, nanometer e ka ba karolo ea limilione tse likete tse le 'ngoe ea mithara, kapa e tšesaane ka makhetlo a likete tse lekholo ho feta moriri oa motho. Ka tekanyo ena, thepa ea 'mele, ea lik'hemik'hale le ea baeloji ea lintho tse bonahalang e ka fapana haholo le thepa ea tsona sekaleng se seholo.
Histori e Khutšoanyane ea Nanotechnology
Khopolo ea nanotechnology e ile ea hlahisoa ka lekhetlo la pele ke setsebi sa fisiks se tummeng Richard Feynman puong ea hae ea 1959, "Ho na le Sebaka se Sengata Botlaaseng." Feynman o ne a nahanne ka bokhoni ba ho laola le ho laola liathomo le limolek'hule ka ho toba. Lentsoe "nanotechnology" ka bolona le ile la sebelisoa ka lekhetlo la pele ke Norio Taniguchi ka 1974, empa e bile ho fihlela lilemong tsa bo-1980 le bo-1990 moo theknoloji e ileng ea qala ho hola ka potlako ka lebaka la ho qaptjoa ha lisebelisoa tse ncha tse kang microscope ea scanning tunneling (STM) le microscope ea matla a athomo (AFM).
