英文摘要The rapid and cost-effective detection of bacteria is of great importance in various fields. Herein, a novel colorimetric detection method for Gram-negative bacteria based on the inhibition of the aggregation of 4-mercaptophenylboronic acid functionalized AgNPs (MPBA-AgNPs) was demonstrated. MPBA, one of the boronic acid derivative, which could react with the cis-diol groups contained in saccharides on the bacteria cells, was used as the recognition molecule for bacteria detection. The aggregation of MPBA-AgNPs could be inhibited by bacterial cells, resulting in different color change, which could be distinguished with UV-vis spectrometer and the naked eye. The concentration of E. coli, a model of Gram-negative bacteria, could be determined in a dynamic range from 5 x 10(4) cfu mL(-1) to 1 x 10(7) cfu mL(-1) with a LOD of 0.9 x 10(4) cfu mL(-1) with fast response of 20 min. Meanwhile, a smartphone based measuring analysis was established to make it suitable for routine laboratory applications. Moreover, the concept of the MPBA-AgNPs based colorimetric strategy could be expanded to other Gram-negative bacteria suggesting a universal platform for bacterial assay. (C) 2018 Elsevier B.V.
