Detection of NF-κB p50 Using a Biosensing Platform Based on In Situ Nanozyme on PbTiO3 Surface
A biosensing platform for the detection of NF-κB p50 was constructed,based on an ,in situ, nanozyme with adjustable catalytic activity.The ,in situ, nanozyme was obtained by combining K,4,Fe(CN),6, onto the surface of PbTiO,3,.Generally,the attachment of deoxyribonucleoside 5'-monophosphate(dNMP) onto the PbTiO,3, surface may prevent the spontaneous formation of nanozyme on its surface,while in the presence of NF-κB p50,dNMP is hardly to be generated,which allows K,4,Fe(CN),6, combining smoothly to the surface of PbTiO,3,,and a spontaneously formed nanozyme on PbTiO,3, surface catalyzes TMB oxidation for the quantitative detection of NF-κB p50.The results showed that the detection linear range of this method for NF-κB p50 was 3.0 pmol/L-10 nmol/L,while the limits of detection(,S,/,N ,= 3) was 1.2 pmol/L.The spiked recoveries for real samples ranged from 99.1% to 102%,with relative standard deviations not more than 5.3%.This method provides a new strategy in label-free,immobilization-free mode for the detection of NF-κB p50 with amplified signal,which not only has high sensitivity,good selectivity and simple operation,but also has an application potential in the detection of actual samples.
