“…Compared with traditional hydrogels, ionogels, which were composed of a polymer network and numerous ionic liquids (ILs), are more suitable to adapt to harsh environments. 7–10 ILs possess not only excellent ionic conductivity and thermal stability but also strong interaction with polymer chains. Therefore, it is a promising strategy to design ionogels as flexible strain sensors for long-term application.…”

“…This color phenomenon was similar to the antibacterial agent based on AgNPs and Fe 3 O 4 -loaded chitin microspheres previously reported by Yu [ 27 ]. Under acidic conditions, H 2 O 2 may be broken down to hydroxyl radicals on the surface of AgNPs inside of Dap-AgNPs, and hydroxyl radicals caused the color of the solution to change from colorless TMB to blue oxTMB [ 28 ]. Dap enhanced the stability of the Dap-AgNPs in solution and made them catalytically active.…”

Silver nanoparticles as photothermal agents have the problems of low stability and low photothermal conversion efficiency. Amphiphilic daptomycin can improve the stability of silver nanoparticles, thereby improving their photothermal conversion efficiency. Herein, daptomycin-biomineralized silver nanoparticles (Dap-AgNPs) were prepared by reducing silver nitrate with sodium borohydride in the presence of daptomycin as a stabilizer and biomineralizer. The Dap-AgNPs had good solution stability and peroxidase-like activity. Furthermore, the photothermal conversion efficiency of the Dap-AgNPs was as high as 36.8%. The Dap-AgNPs displayed good photothermal stability under irradiation. More importantly, the Dap-AgNPs showed good cell compatibility with HeLa cells and HT-29 cells without irradiation by 808-nanometer near-infrared light at a concentration of 0.5 mM, and the cell viability was greater than 85.0%. However, the Dap-AgNPs displayed significant anti-tumor ability with irradiation by 808-nanometer near-infrared light, which was due to the increasing temperature of the culture medium caused by the Dap-AgNPs. In conclusion, Dap-AgNPs have potential applications as photothermal agents in the treatment of tumors.

“…The catalytic activity of natural enzymes was greatly affected by temperature and pH. [28,29] In order to make Pd-LNT NPs maintain the highest catalytic activity, we optimized the conditions at different temperature and pH. Figure 4a showed that the Pd-LNT NPs had the highest catalytic activity at 30 °C, and Figure 4b showed the highest catalytic activity of Pd-LNT NPs when pH 4.Therefore, the optimal catalytic conditions of Pd-LNT NPs were 30 °C and pH 4, which was the same as the previously reported work.…”

Natural enzymes are special proteins with excellent catalytic activity and selectivity. It is difficult to purify, store without losing the catalytic ability. Therefore, it is of great significance to study mimetic enzymes to realize the functions of natural enzymes and overcome their shortcoming. Herein, lentinan was used as a biological template to prepare palladium nanoparticles stabilized by lentinan (Pd‐LNT NPs), whose structure, activity and function were characterized. In addition, the 3,3′,5,5′‐tetramethylbenzidine (TMB) was oxidized by Pd‐LNT NPs in the presence of H2O2, which proved that they had good peroxidase‐like activity. The optimum reaction conditions were 30 °C and pH 4, the catalytic kinetic parameters were consistent with Michaelis‐Menten equation, and the good catalytic performance was verified. Furthermore, the colorimetric reaction based on the good peroxidase‐like activity of Pd‐LNT NPs was used for the convenient detection of H2O2. The linear range of colorimetric detection of H2O2 was 3.571‐107.143 μM, and it is worth noting that the detection limit was low to 4.714 μM. At last, Pd‐LNT NPs as biomimetic enzymes were used to detect the H2O2 released from HeLa cells, indicating they have great potential in the field of biological application.
