Cov Nanoparticles tuaj yeem ua haujlwm nrog cov ligands tshwj xeeb rau cov receptors ntawm qhov chaw ntawm cov hlwb lub hom phiaj. Piv txwv li, siv cov tshuaj tiv thaiv kab mob ua cov ligands tso cai rau cov nanoparticles kom paub thiab khi rau cov hlwb mob qog noj ntshav tshwj xeeb. Yog li ntawd, cov tshuaj encapsulated tuaj yeem tso tawm ncaj qha mus rau hauv cov hlwb mob qog noj ntshav, txo qhov kev puas tsuaj rau cov hlwb noj qab haus huv thiab txo cov kev mob tshwm sim.
Kev Kuaj Mob thiab Kev Thaij Duab
Ntxiv rau nws lub luag haujlwm ua ib qho cuab yeej xa tshuaj, nanotechnology kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov cuab yeej kuaj mob thiab duab. Cov nanoparticles ua haujlwm tau siv los ntes cov kab mob biomarker molecules thaum ntxov, txhim kho qhov tseeb ntawm kev kuaj mob thiab txo qhov xav tau cov txheej txheem invasive.
Ib qho piv txwv ntawm kev siv cov nanoparticles hauv kev thaij duab yog kev siv cov quantum dots, cov semiconductor nanoparticles uas tso tawm lub teeb ntawm ntau qhov sib txawv thaum ci. Quantum dots tuaj yeem hloov kho kom paub txog cov biomarker molecules tshwj xeeb, xws li cov protein tsim los ntawm cov hlwb qog noj ntshav, ua rau pom thiab saib xyuas kev loj hlob ntawm qog noj ntshav thaum ntxov.
Cov khoom me me Ferrite, uas muaj hlau oxide, kuj siv ntau zaus hauv kev thaij duab magnetic resonance imaging (MRI). Los ntawm kev tswj cov teb magnetic, cov khoom me me no tuaj yeem tsim cov duab sib piv zoo dua, pab cov kws kho mob txheeb xyuas thiab nrhiav cov qog nqaij hlav nrog qhov tseeb dua.
Nanotechnology hauv Kev Kho Mob Gene
Kev kho mob noob caj noob ces yog ib txoj kev kho mob uas hloov pauv tas li uas tsom mus rau kev kho lossis hloov cov noob caj noob ces uas puas lawm. Nanotechnology muab cov txheej txheem xa khoom zoo rau cov khoom siv noob caj noob ces, xws li DNA, RNA, lossis CRISPR-Cas9. Piv txwv li, cov lipid nanoparticles tuaj yeem siv los qhwv cov khoom siv noob caj noob ces, tiv thaiv nws kom tsis txhob puas tsuaj thiab pab kom nws nkag mus rau hauv cov hlwb uas xav tau.
Ib qho kev nce qib tseem ceeb hauv daim teb no yog kev tsim cov nanoparticles uas ua raws li liposome, uas tau siv rau hauv kev kho mob me me uas cuam tshuam nrog RNA (siRNA) rau kev kho mob ntawm ntau yam mob caj ces. Nanotechnology tso cai rau siRNA xa mus rau cov hlwb tshwj xeeb, txwv tsis pub cov noob caj ces cuam tshuam nrog kab mob thiab txo qhov kev pheej hmoo ntawm cov kev mob tshwm sim.
