Abstract：

Tungsten　disulfide　(WS2)　nanosheets　were　discovered　to　possess　intrinsic　peroxidase-like　activity　and　catalyze　the　peroxidase　substrate　3,3＇,5,5＇-tetramethylbenzidine　(TMB)　to　produce　a　color　reaction　in　the　presence　of　H2O2.　Based　on　this　finding,　a　colorimetric　method　and　a　portable　test　kit　for　the　visual　detection　of　blood　glucose　have　been　developed　by　using　glucose　oxidase　(GOx)　and　WS2　nanosheets-catalyzed　reactions.　The　linear　range　for　glucose　was　ranged　from　5　to　300μM　(R2=0.999)　with　the　detection　limit　of　2.9μM.　The　portable　test　kit　was　successfully　evaluated　glucose　levels　in　serum　samples　from　normal　persons　and　diabetes　persons　by　the　observable　color　change　from　pale　yellow　to　yellow-green,　blue-green.　©　2014　Elsevier　B.V.
