Although glucose electrochemical sensors based on enzymes play a dominant role in market, their stability remains a problem due to the inherent nature of enzymes. Therefore, glucose sensors that are independent on enzymes have attracted more attention for the development of stable detection devices. Here we present an enzyme-free glucose sensor based on Ni(OH)(2) and reduced graphene oxide (rGO). The as-fabricated sensor still exhibits excellent electrocatalytic activity for detecting glucose under enzyme independent conditions. The enhanced catalytic performance may due to synergistic effect as follows: (i) the interaction between the Ni2+ and pi electron of graphene induces the formation of the beta-phase Ni(OH)(2) with higher catalytic activity; (ii) the frozen dry process works as a secondary filtration, getting rid of poorly formed Ni(OH)(2) particles with low catalytic activity; (iii) the rGO network with good conductivity provides a good electronic pathway for promoting electron transfer to reduce the response time. Based on the synergistic effect, the sensor exhibits a wide linear detection range from 0.2 mu mol/L to 1.0 mu mol/L and a low detection limit (0.1 mu mol/L, S/N=3). The excellent detection performance, as well as the easy and low-cost preparation method, suggests the promising applicability of the sensor in the glucose detection market.

BACKGROUND:There are currently no effective drugs to mitigate the ischemia/reperfusion injury caused by fluid resuscitation after hemorrhagic shock(HS).The aim of this study was to explore the potential of the histone deacetylase 6(HDAC6)-specific inhibitor tubastatin A(TubA)to suppress nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)inflammasome activation in macrophages under hypoxia/reoxygenation(H/R)***:The viability of RAW264.7 cells subjected to H/R after treatment with different concentrations of TubA was assessed using a cell-counting kit-8(CCK8)***,2.5μmol/L TubA was used with RAW264.7 cells under H/R ***264.7 cells were divided into three groups,namely the control,H/R,and TubA *** levels of reactive oxygen species(ROS)in the cells were detected using fluorescence *** protein expression of HDAC6,heat shock protein 90(Hsp90),inducible nitric oxide synthase(iNOS),NLRP3,gasdermin-D(GSDMD),Caspase-1,GSDMD-N,and Caspase-1 p20 was detected by western *** levels of interleukin-1β(IL-1β)and IL-18 in the supernatants were detected using enzyme-linked immunosorbent assay(ELISA).RESULTS:HDAC6,Hsp90,and iNOS expression levels were significantly higher(P<0.01)in the H/R group than in the control group,but lower in the TubA group than in the H/R group(P<0.05).When comparing the H/R group to the control group,ROS levels were significantly higher(P<0.01),but significantly reduced in the TubA group(P<0.05).The H/R group had higher NLRP3,GSDMD,Caspase-1,GSDMD-N,and Caspase-1 p20 expression levels than the control group(P<0.05),however,the TubA group had significantly lower expression levels than the H/R group(P<0.05).IL-1βand IL-18 levels in the supernatants were significantly higher in the H/R group compared to the control group(P<0.01),but significantly lower in the TubA group compared to the H/R group(P<0.01).CONCLUSION:TubA inhibited the expression of HDAC6,Hsp90,and iNOS in macrophages
