The invention provides a chlorine dioxide-containing disinfectant hand sanitizer, which consists of a surfactant, a chelating agent, a moisturizing agent, a thickener, a water-soluble emollient, a bactericide precursor, a pH regulator, an essence and deionized water Made according to a certain weight ratio. The disinfectant hand sanitizer provided by the invention is mild in nature, safe and environmentally friendly, and realizes cleaning, skin care, and sterilization simultaneously. Chlorine dioxide is selected as the bactericide component, and the bactericidal effect is good, the action time is short, and the sterilizing rate is high, and bacteria will not Tolerance to it is produced, and it takes effect immediately after use. In addition, the hand sanitizer of the present invention will not produce carcinogens such as chloroform during use, and the biodegradation rate of all surfactants is also more than 90%, which meets national requirements and is environmentally friendly. Toxic, harmless, safe and environmentally friendly, people can safely use this product for a long time.

The invention discloses a preparation method for coffee and natural plant powder composite particles and application of the coffee and natural plant powder composite particles to a cigarette filter. The preparation method includes: uniformly mixing coffee powder, sweetening natural plant powder and porous corn starch according to a certain proportion, moistening the mixture with deionized water containing reducing sugar, and then performing wet granulation, microwave setting, microwave drying and sieving to obtain high-strength natural products, namely power composite porous starch crystalline particles. The particles are loaded in the cigarette filter to prepare a binary or ternary composite filter, so that content of harmful ingredients such as tar and CO in smoke can be lowered, cancerogens of benzo[a]pyrene, phenol and the like are reduced, and content of unique coffee volatile fatty acids in the smoke can be increased. Cigarette sense organ smoke panel tests show that by adding the coffee and natural plant powder composite particles in the filter, aroma of the cigarette smoke can be enhanced, aroma quality and harmony are improved, offensive odor and irritation are reduced, sweet feeling is added, and inherent quality of a cigarette is improved integrally.

The invention discloses a preparation method of an iodine-containing dressing. According to the invention, glycerin and polyethylene glycol are used for coating iodine to form microcapsules; on the premise that an antibacterial effect is guaranteed, a slow release effect is improved, the irritation of the dressing to the skin is reduced, the hygroscopicity of the dressing can be improved, and theuse comfort of the dressing is improved. According to the preparation method, three types of carcinogens-polyvinylpyrrolidone can be avoided, so the obtained dressing is higher in safety.

An animal model is provided which is genetically engineered to express human serum albumin, and such animals may be advantageously used in assessing drugs, vaccines or other therapeutic compounds that may be used in humans. In addition, an animal model is provided which does not manufacture its own albumin and which has been injected with human serum albumin. Through the use of these animal models, drugs and other chemicals can be more accurately assessed in physiological environments that reflect the conditions to be expected in humans, and such models will be useful in assessing new drugs and evaluating toxic substances for potential dangers as carcinogens, mutagens, etc. Other applications include evaluating immunological properties of various albumin-engineered proteins which might be administered to humans as therapeutics or vaccines, and research of disease states, such as genetic diseases, to provide further insight in treating these diseases.

The invention discloses a secondary crosslinking post-modification method of a polymeric adsorbent. The secondary crosslinking post-modification method comprises the following steps: epoxying and activating a residual double bond on a poly styrene-co-divinyl benzene resin, forming a polyhydroxy surface through hydrolysis, and enabling a hydroxide radical and an epoxy group to perform secondary crosslinking. The hydrophobic polymeric adsorbent forms the polyhydroxy surface through activation and hydrolysis, the hydrophily is improved, the modified functional group is also provided, and the polymeric adsorbent does not need to be modified on a benzene ring. The epoxy chloropropane is used for secondary crosslinking to obtain a poly styrene-co-divinyl benzene resin microsphere with higher strength and more stable space structure. The chloromethyl ether with strong cancerogen or the expensive vinylbenzyl chloride is not used, and the cost is relatively low. The invention further discloses the polymeric adsorbent prepared through the secondary crosslinking post-modification method and a blood perfusion device using the polymeric adsorbent.
