Tsis ntev los no, pab pawg tshawb fawb ntawm tus kws tshawb fawb Shao Yuchuan los ntawm Shanghai lub koom haum ntawm Optical Precision Machinery, Suav Academy ntawm Kev Tshawb Fawb, tau npaj ib lub tswv yim tshiab los siv cov nyhuv photothermal ntawm kub nanoparticles rau kev npaj kho qhov muag PUFs, thiab cov txiaj ntsig kev tshawb fawb muaj feem cuam tshuam nrog. "Lub cev Unclonable Functions raws li Photothermal nyhuv ntawm Kub Nanoparticles". Cov txiaj ntsig kev tshawb fawb tau luam tawm hauv ACS Applied Materials & Interfaces hauv qab lub npe "Photothermal Effect of Gold Nanoparticles".
Tam sim no, cov ntawv cim kev ruaj ntseg feem ntau tuaj yeem ua tau yooj yim vim lawv cov txheej txheem tsim khoom ruaj khov. Lub Cev Muaj Zog Unclonable Functions (PUFs) siv cov txheej txheem kev npaj uas tsis tuaj yeem sib txawv ntawm cov ntaub ntawv thaum lub sijhawm npaj, uas tuaj yeem tsim cov cim thiab cov lus teb tsis txaus ntseeg raws li cov lej tiv thaiv cuav. Ib yam li tsis muaj ob nplooj zoo tib yam hauv ntiaj teb, txawm tias cov chaw tsim khoom tsis tuaj yeem ua ob lub PUF zoo tib yam. Txawm hais tias kho qhov muag PUFs tau nyiam ntau qhov kev mloog vim lawv lub peev xwm encoding siab thiab cov lus teb zoo sib xws, lawv tseem ntsib ntau yam teeb meem: cov lus teb cov cim ntawm kev tawg PUFs tsis ruaj khov, lub neej ntawm fluorescent PUFs raug hem los ntawm fluorescence bleaching, thiab cov ntaub ntawv pov thawj. ntawm Raman PUFs yog qhov nyuaj thiab yuav tsum tau siv cov khoom siv decoding kim heev. Cov tiam tom ntej ntawm optical PUFs yuav xav tau kev tiv thaiv kab mob-immunoprecipitation. Tom ntej no-tiam kho qhov muag PUFs xav tau lub peev xwm ntawm immunofluorescence thiab Raman excitation, yog li hauv paus tshem tawm cov kev cuam tshuam ntawm cov khoom nws tus kheej tsis xws luag ntawm kev nyab xeeb kev ua tau zoo ntawm optical PUFs.
Cov kws tshawb fawb tau tawm tswv yim tshiab los npaj kho qhov muag PUFs siv cov nyhuv nanogold photothermal. Cov txheej txheem pib nrog kev ua kom zoo dua qhov chaw ntom ntom nti thiab tsim cov teeb meem ntawm cov khoom siv sib txawv thiab tsim cov lus teb yooj yim txaus. Qhov zoo tshaj plaws ntawm qhov ntom ntom ntawm kub nanoparticles tau ua tiav los ntawm kev txhim kho cov txheej txheem kev npaj kom ua kom muaj peev xwm ua tau zoo tshaj plaws ntawm PUF. Cov kev npaj kho qhov muag PUF tsis tsuas yog ua tau raws li PUF kev ua tau zoo xws li qhov tsis sib xws, kev ntseeg tau, thiab kev sib txawv me ntsis, tab sis nws cov lej zais zais kuj dhau los ntawm NIST random tus lej xeem txhawm rau txheeb xyuas nws qhov tsis sib xws. Txoj haujlwm no muab kev txhawb nqa muaj zog rau kev ua tiav ntawm daim ntawv thov ntawm cov nyhuv photothermal ntawm optical PUF.
