Abstract: A multi-enzyme cascade antioxidant nano HOF and preparation method and application thereof are provided. The present invention discloses a nano HOF based on selenium-containing ligand for the first time, the nano HOF does not contain metal and has good biocompatibility, which is a universal loading platform, and has high porosity, acid and alkali resistance and thermal stability, and is size-tunable, it can coat various types of enzymes at the same time, stabilize the conformation of the enzyme through the confinement effect, the high porosity can not only provide enough space for the enzyme, but also facilitate the transport of substances and the play of catalytic properties of the enzyme, 85-90% of the activity of the coated enzyme can be maintained, ROS can be effectively scavenged through the cascade catalysis between various enzymes, which provides a new idea for the construction of bio-friendly antioxidants.

Abstract: A dual-modal information storage and anti-counterfeiting material, and its preparation method are provided. The dual-modal information storage and anti-counterfeiting material uses cadmium sulfide quantum dots (CdS QDs) as information storage material, and uses the controllable photocorrosion of CdS QDs to achieve dual-modal optical information storage and anti-counterfeiting applications. Firstly, the type of ligands and modification degree of CdS QDs are precisely controlled during the aqueous phase synthesise process, so as to effectively control the photocorrosion phenomenon under UV light irradiation. Subsequently, the CdS QDs are loaded in the hydrogel network, and they are also loaded on the substrates such as cloth and paper by spray coating, dip coating or 3D printing, and the information is stored by digital light patterning. Different from the photochromic function of traditional anti-counterfeiting material, the CdS QDs shows dual-modal patterning characteristics in a wide wavelength range.

Abstract: Disclosed are a cis-platinum cross-linked protein hydrogel and a preparation method thereof. Main components of the cis-platinum cross-linked protein hydrogel comprise the following ingredients in percentage by mass: 0.5% to 5.0% drug, 6.0% to 50.0% serum albumin and 47.0% to 93.0% solvent medium; a carboxyl group on a surface of the serum albumin and the drug form a coordinate bond; and the drug is cis-platinum. A hydrogel preparation is simple in structure and easy to prepare, and the used cis-platinum has dual effects: a cross-linking agent for promoting the formation of protein hydrogels and an antitumor drug for exerting a tumor inhibition curative effect. The strategy simplifies the carrier design and reduces potential toxic side effects. The protein carboxyl limits the release of cis-platinum through a coordination effect so that reduce the burst release of the loaded drugs drastically.

Abstract: The present invention concerns an optical coupling device including at least one supporting layer comprising a first support wall and a second support wall. The at least one supporting layer comprises at least one bridging waveguide for coupling electromagnetic radiation to and from an optical resonator or optical device, the at least one bridging waveguide extending between the first support wall and the second support wall.

Abstract: A dual-frequency-comb spectrometer and a method for spectroscopic investigation of a sample are described. The spectrometer includes first and second frequency comb devices for emitting laser pulses along first and second light paths, wherein the repetition frequency of the laser pulses emitted by the second device is offset from that of the first device. First and second multi-core waveguides including at least two separate single core waveguides having field-coupling via a coupling gap therebetween are arranged in the first and second light paths. The sample is irradiated by the second frequency comb in the second light path. A detector device is arranged in a third light path where the first and second light paths are combined, for simultaneously sensing the first frequency comb and the second frequency comb after an interaction with the sample. A computing device receives output of the detector device and calculates spectroscopic properties of the sample.
