N'inye ọgwụ, ngwa nanotechnology na-ekwe nkwa mmụba arụmọrụ, belata mmetụta ọjọọ, na usoro kachasị mma e nyere na mpaghara ahụ.
Akụkọ Dị Mkpirikpi nke Nanotechnology na Ọgwụ
Ndị ọkà mmụta sayensị maara teknụzụ nano nke ọma na mbido afọ 1980, mana echiche nke nhazi nanoscale adịla kemgbe mmalite narị afọ nke 20. Ngwa nke nanotechnology na ọgwụ malitere itolite ngwa ngwa mgbe achọpụtara ma meziwanye usoro dị iche iche maka imepụta na ịkọwapụta nanomaterials. Ka teknụzụ na-aga n'ihu, ndị nchọpụta malitere ịchọpụta otu esi eji nanoparticles emeso nsogbu dị iche iche nke nnyefe ọgwụ.
Usoro dị mkpa nke nnyefe ọgwụ na-adabere na Nano
Nnyefe ọgwụ sitere na nano gụnyere ọtụtụ usoro dị iche iche, gụnyere nanoparticles, nanocapsules, liposomes, dendrimers, na nanotubes. Usoro ọ bụla nwere njirimara pụrụ iche nke na-emetụta otu esi etinye ọgwụ ahụ n'ime ahụ, nye ya, na ịtọhapụ ya.
1. Nanoparticles: Ihe owuwu ndị a nwere ike ịnabata ọgwụ n'ime ma ọ bụ n'elu ha. A na-ejikarị ihe dịka polima, lipids, ma ọ bụ ọla ndị a kapịrị ọnụ nke ahụ nwere ike ịgbawa ma ọ bụ mịnye. Uru ha bụ ikike ijikwa mwepụta ọgwụ ma mee ka bioavailability dịkwuo elu.
2. Nanocapsules: Mkpụrụ ọgwụ ndị a na-etinye ọgwụ ahụ n'ime ahụ, na-echebe ya ka ọ ghara imebi ruo mgbe o ruru ebe a chọrọ ya. Enwere ike ịhazi ha ka ha wepụta ọgwụ ahụ ka ọ na-agafe n'ime arịa ọbara nke etuto ahụ, nke na-enwekarị oghere buru ibu karịa nke dị n'ime anụ ahụ dị mma.
3. Liposomes: Ọdịdị dị ka vesicle nke akwa lipid mepụtara. Liposomes nwere ike ibu ma ọgwụ lipophilic (nke na-agbaze abụba) n'ime akpụkpọ ahụ ha na ọgwụ hydrophilic (nke na-agbaze mmiri) n'ime isi mmiri ha. Lipid bilayer na-eme ka liposomes kwekọọ n'ụzọ ebumpụta ụwa ma nwee ike ibute mkpụrụ ndụ n'enweghị nsogbu.

5. Nanotubes: Tube cylindrical nke e ji carbon ma ọ bụ ihe ndị ọzọ mee. Nanotubes nwere ike ibu ọgwụ site na endocytosis ma nye ọgwụ na-aga n'ihu.
Uru nke Nanotechnology na nnyefe ọgwụ
Uru dị na nanotechnology n'ọgwụ na nnyefe ọgwụ dị iche iche ma dị mkpa. Lee ụfọdụ n'ime uru ndị bụ isi:
1. Mmụba na Ịkwụsi Ike Ka Mma: Ọtụtụ ọgwụ nwere nsogbu na ịgbaze na mmiri ahụ, nke na-ebelata irè ha. Nanoparticles nwere ike ime ka ọgwụ gbaze na mmiri na mmiri bayọlọji dịkwuo mma, na-eme ka bioavailability na nkwụsi ike dịkwuo mma.
2. Nnyefe Ezubere: Otu n'ime ihe ịma aka kachasị na ọgwụgwọ ọgwụ bụ ijide n'aka na ọgwụ ndị ahụ ruru ebe kwesịrị ekwesị n'ahụ. Site na nanotechnology, enwere ike itinye ọgwụ n'ime ihe ndị na-emekọrịta naanị na mkpụrụ ndụ na anụ ahụ kpọmkwem. Dịka ọmụmaatụ, enwere ike iji ligands kpuchie nanoparticles nke na-amata mkpụrụ ndụ kansa, na-enye ọgwụgwọ dị irè karị ma belata mmetụta ọjọọ.
3. Ntọhapụ A Na-achịkwa: Nanotechnology na-enye ohere maka mwepụta ọgwụ a na-achịkwa, ma n'ime oge ma ọ bụ n'ihi ọnọdụ gburugburu ebe obibi dị iche iche dị n'ahụ dịka pH ma ọ bụ okpomọkụ.
4. Mbanye n'ime anụ ahụ na mkpụrụ ndụ: Obere obere nke obere nanoparticles na-enye ha ohere ịbanye n'ime mkpụrụ ndụ na akpụkpọ anụ ahụ nke ọma, na-enye ọgwụgwọ dị irè karị.
5. Nchedo Ọgwụ: Ọtụtụ ọgwụ na-emebi ngwa ngwa tupu ha erute ebe ha chọrọ. Nanoparticles nwere ike ichebe ọgwụ site na enzymes ma ọ bụ imebi ọnọdụ gburugburu ebe obibi, na-eme ka ha dị irè ruo mgbe ha ruru ebe ha chọrọ.
Ngwa Ọgwụ nke Nnyefe Ọgwụ Dabere na Nano
Ọtụtụ ojiji ahụike nke nnyefe ọgwụ nano enwetawo nlebara anya na ihe ịga nke ọma dị ukwuu:
1. Ọrịa Kansa: Otu n'ime ihe ndị kacha enye aka bụ ọgwụgwọ kansa. Enwere ike imepụta nanoparticles iji lekwasị anya ma bibie mkpụrụ ndụ kansa n'emebighị mkpụrụ ndụ dị mma gbara ya gburugburu. Dịka ọmụmaatụ, ejirila Doxil, ụdị liposomal nke doxorubicin, agwọ ọrịa kansa ovarian.
2. Ọrịa ndị na-emebi akwara: Inye ọgwụ n'ụbụrụ bụ nnukwu ihe ịma aka n'ihi ihe mgbochi ọbara na ụbụrụ. Nanotechnology na-enye nnukwu ikike n'imeri ihe mgbochi a ma na-enye ọgwụgwọ maka ọrịa dịka Alzheimer na Parkinson.
3. Ọrịa Bakteria na Virus: Egosila na mkpụrụ ndụ ọlaọcha dị irè n'igbu nje bacteria na nje site n'ịkpaghasị usoro nke akpụkpọ ahụ nje bacteria. Na mgbakwunye, mkpụrụ ndụ nje nwere ike ibu ọgwụ nje ma ọ bụ ọgwụ nje iji mee ka ha dịkwuo irè.
4. Ọrịa shuga: Usoro nnyefe ọgwụ nke dabere na nano nwere ike inye aka n'ịhazi mwepụta insulin, na-enye njikwa glucose ọbara ka mma ma na-adịgide adịgide.
Ihe Ịma Aka na Echiche Ọdịnihu
N'agbanyeghị na ọ na-enye ọtụtụ uru, nnyefe ọgwụ nano ka na-eche ọtụtụ ihe ịma aka ihu:
