In Chinese as Reuters Professor Cui China Science and Technology Research Group in collaboration with Prof. and Methodologies, Part Nanjing University Professor Wang, successful long and having a high strength hydrogels prepared chemiluminescence, luminescence visible in the dark And lasted for more than 150 hours, and proposed a new "glow" type chemiluminescence mechanism - the mechanism of heterogeneous catalysis of slow diffusion control. Related research results were published online on October 17th under the title "Firefly-mimicking intensive and long-lasting chemiluminescence hydrogels" on Nature Communications (Nat. Commun., 2017, DOI:10.1038/s41467-017-01101- 6). ▲ Preparation and chemiluminescence of chemiluminescent hydrogel At present, most chemiluminescence reactions are "flash" type light emission, and the illumination is completed in a short time, which limits its application in cold light source, analytical chemistry and biological imaging. High-intensity and long-term "glow" chemiluminescence has always been the goal pursued in the field of chemiluminescence. Research Results The research team used a natural chitosan, chemiluminescent reagent N-(4-aminobutyl)-N-ethylisoluminol (ABEI) and a catalyst Co2+ to prepare a hydrogel. The study found that 99.8% of Co2+ was immobilized on the hydrogel backbone, while 89.5% ABEI was dispersed in the hydrogel pores. When the oxidant H2O2 is added, it slowly diffuses into the hydrogel, which is decomposed by the catalyst Co2+ at the active center to produce active radicals, which are then reacted with a chemiluminescent reagent to produce chemiluminescence. The chelation and heterogeneous action of Co2+ enhances its catalytic activity and stability, and the hydrogel with micro/nano pores and high viscosity greatly reduces the diffusion rate of H2O2, resulting in strong and long chemiluminescence. This work simulates firefly bioluminescence in terms of chemiluminescence kinetics and catalytic properties, and its luminescence time is significantly better than existing long-term chemiluminescence systems, such as enzyme-involved chemiluminescence systems and peroxy oxalate chemiluminescence systems. The hydrogel has simple synthesis, environmental friendliness and good biocompatibility, and has important application potential in cold light source, biosensor, microchip and biological imaging. Editor: Yan Zhixiang The Hydrogel Screen Protector is made of imported material with TPU as the base material and is combined with hydrogel. It has super ductility and retractability, and can perfectly adapt to curved screens and screens with excessively curved edges, so as to fit perfectly without leaving white edges, and basically does not affect the touch experience. It has a strong and effective self-healing function, is impact-resistant, durable, and has better toughness, and has a certain buffering effect on the collision of sharp objects.

The Hydrogel Screen Protector uses glue and hydrogel to activate the stickiness to ensure a perfect fit without warping and leaving blanks, which is more beautiful. The Hydrogel Film is very thin. The responsive, ultra-thin design gives you a bare-bones experience. It's not as thick as a Tempered Glass Screen Protector, so the hydrogel screen protector won't affect the weight and feel of the phone.
In terms of hand feel, the Hydrogel Screen Protective Film has a hydrophobic and oleophobic treatment, so it slides relatively smoothly, and there is no problem in using APP or playing games. In addition, the liquid spilled on it can be slipped off by just tilting it, which is very easy to clean and maintain.
