2. Representative Research Achievements
(1)In traditional lateral flow immunoassays (LFIA) for pathogens detection, capture antibody (CA) is necessary and usually conjugated to Au nanoparticles (NPs) in order to label the target analyte. However, the acquisition process of the Au−CA nanoprobe is relatively complicated and costly, which will limit the application of LFIA. Herein, p-mercaptophenylboronic acid-modified Au NPs (namely Au−PMBA nanocrabs), were synthesized and applied for a new CA-independent LFIA method. This CA-independent strategy exhibited higher sensitivity than the traditional CA-dependent double antibody sandwich method, because detection limit of the former one was 103 cfu/mL only by visual observation, which was reduced by 3 orders of magnitude. This CA-independent LFIA showed great advantages and satisfactory potential for rapid foodborne pathogens detection in real sample.
(2)Bacterial infections with a high mortality rate have become serious health issues for human beings. Current treatment remains unsatisfactory due to the limited antibacterial efficacy triggered by weak tissue and biofilm permeability of drugs and the risk of antibiotic resistance. To address these issues, a novel enzymatic antibacterial strategy, is developed with highly peroxidase-like activities. Both in vitro and in vivo experiments exhibit superior synergistic antibacterial efficacy. The antimicrobial mechanisms are explained as the reduction of natural enzyme activities and the disruption of cell walls and membranes along with the production of abundant •OH radicals derived from nanozymes, which provides a potential platform for future synergistic antibacterial application.
