Selective labeling of distinct bacteria and biofilm is poised for the fundamental understanding of bacterial activities, interactions, and coupled phenomena occurring at the microscale. However, a simple and effective way to achieve selective bacterial labeling is still lacking. Herein, we report a fluorescence probe with core-shell nanostructure that has polydopamine (PDA) coating on the surface of fluorescent silicon quantum dots (SiQDs@PDA). The surface of the SiQDs@PDA can be functionalized by various molecules (2-mercaptoethylamine hydrochloride, PEG, d-alanine, glucose amide) through different strategies (Michael addition, π-π interaction, and ion-ion interaction). Importantly, the d-alanine (D-Ala)- and gluconamide (Glc)-functionalized SiQDs@PDA fluorescence probes are capable…

In order to compare the influence of the manufacturing methods on the property of silicone samples, the latticed structure of sample are designed, the silicone material is prepared and the silicone sample are produced by 3D printing and injection molding respectively. Four performance indexes of latticed silicone parts including the error of line width, the error of quality, tensile strength at break and elongation at break are proposed and measured. A fuzzy comprehensive evaluation system for evaluating the optimal forming method of the parts is provided. The performance indexes are used as evaluation factors, and the importance degree of the…
