The application belongs to the technical field of antitumor drugs, and particularly relates to an AuNRs@L / D-Ag2S QDs complex, a preparation method and application thereof. Sodium polystyrene sulfonate is electrostatically adsorbed on AuNRs to obtain 1-PSS-AuNRs; polyallylamine hydrochloride is electrostatically adsorbed on 1-PSS-AuNRs to obtain 2-PAH-AuNRs; polyallylamine hydrochloride is electrostatically adsorbed on 2-PAH-AuNRs to obtain a non-chiral nanomaterial; and the non-chiral nanomaterial is covalently crosslinked with L / D-Ag2S QDs to obtain the AuNRs@L / D-Ag2S QDs complex. The application combines the efficient photo-thermal conversion characteristics of AuNRs with the chiral-dependent targeting and potential fluorescence imaging ability of chiral Ag2S quantum dots by constructing a complex structure, so that a novel nanodiagnostic and therapeutic agent with efficient photo-thermal performance and chiral selectivity is obtained.

The application provides an ultrasonic response piezoelectric ionic hydrogel and application thereof, and the hydrogel is formed by cross-linking and solidification of a precursor solution under ultraviolet irradiation; components of the precursor solution include a photosensitive polymer, an ionic polymer, a photoinitiator and a solvent; the photosensitive polymer includes any one or a combination of at least two of polyether F127 diacrylate, polyhydroxyethyl methacrylate, polyethylene glycol dimethyl acrylate, methacrylated gelatin or methacrylated collagen; and the ionic polymer includes any one or a combination of at least two of epsilon-polylysine, polyethyleneimine hydrochloride, polyallylamine hydrochloride, polyquaternary ammonium salt-10 or cationic guar gum. The application uses ultrasonic waves as an external remote driving signal to non-invasively and painlessly activate the piezoelectric ionic effect of the hydrogel, generate detectable periodic voltage and current signals in the hydrogel, and has excellent treatment effect on acne and infected wound repair.

The present application belongs to the field of gel electrolyte, and discloses a hydrolysis-resistant Schiff base hydrogel electrolyte for supercapacitors, and a preparation method and application thereof. The present application utilizes the natural dissociation of polyallylamine hydrochloride in aqueous solution, and does not need to adjust the pH value, so that free amino groups can be released under acidic conditions to occur condensation reaction with glutaraldehyde, and a three-dimensional network crosslinked by Schiff base structure is obtained. The preparation method is simple, does not need organic solvent, and the reaction is controllable, and the gelation can be completed at room temperature in a short time. The obtained hydrogel electrolyte overcomes the defect that the traditional Schiff base structure is easy to hydrolyze under acidic conditions, and has excellent chemical stability. The solid-state supercapacitor assembled by using the in-situ forming capacity effectively solves the problem of poor contact between the electrode and the electrolyte, improves the conductivity, specific capacitance and energy density of the device, and has wide application prospect in the field of flexible energy storage devices.
