The invention discloses heterogeneous micro-patterned hydrogel and a preparation method and application thereof, and the method comprises the following steps: S1, dissolving agar to obtain an agar solution, and injecting the agar solution into a mold to prepare agar gel; s2, mixing methacrylated gelatin and a photoinitiator to obtain a pre-polymerization solution, and soaking the agar glue in the pre-polymerization solution; s3, covering the soaked agar gel with a mask plate, and illuminating the agar gel, so as to obtain heterogeneous micro-patterned hydrogel; wherein the content of agar in the agar solution is 0.5-5 wt%, and the content of methacrylated gelatin in the pre-polymerization solution is 3-30 wt%. According to the hydrogel provided by the invention, the chemical compositions of the adhesion area and the anti-adhesion area are different, so that the cell adhesion capacities and swelling properties of the two areas are different, and the difference of the swelling properties further enables the adhesion area to form bulges compared with the anti-adhesion area, so that the cooperative regulation and control of the chemical compositions and the physical structure are realized; the cell behavior can be accurately regulated and controlled.

A structured cleansing composition comprising a) from 0.1 to 40 wt % of a non-sulphate containing anionic surfactant comprising i) an amino acid head group; ii) an alkyl tail with a carbon-carbon chain length of from C6 to C22, b) from 0.15 to 4 wt % of a polysaccharide selected from the group consisting of agar, agarose, agaropectin and mixtures thereof; and c) an oil; wherein the polysaccharide is in the form of gel particles; wherein the composition has viscosity in the range of from 1,000 to 50,000 mPa.s, preferably from 1,000 to 25,000, more preferably from 2,000 to 25,000 mPa.s, even more preferably from 2,100 to 15,000 mPa.s, when measured at 25 degrees C and 4s-1, using sandblasted 40mm parallel plates, on a Wingspan rheometer (TA instruments); and wherein the composition comprises no added salt.

The invention discloses a screening and compounding method for preparing a lasioderma serricorne food attractant by using a spice monomer, which comprises the following steps: S1, primarily selecting M spice monomer standard substances from a tobacco spice monomer library, and primarily selecting the attractant by using a trapping plate selection device, s2, adopting a monomer with a relatively good attraction effect as a main component, diluting to a certain concentration, testing the attraction effect by using an insect olfactometer, determining the optimal attraction dosage, and compounding according to the principle that the rest are auxiliary components, screening 1-2 formulas with relatively good effects, and determining the compound dosage; and S3, performing porous starch embedding, agar gel inclusion, silica gel pad slow release and other dosage form treatments on the monomer or the formula, and analyzing the residual period by using gas chromatography to determine the optimal carrier dosage form. According to the food attractant, male insects and female insects are trapped, the lasioderma serricorne trapping efficiency is improved, target targeting of the spice monomer and the tobacco homologous odorant is the same, ingredients are definite, quantification is accurate, industrial production is facilitated, and data support is provided for tobacco insect monitoring.

This invention relates to an e-liquid with a refreshing snail flavor and its preparation method, belonging to the field of e-liquid technology. The e-liquid prepared by this invention has a refreshing and long-lasting flavor, a delicate and ethereal aroma, is mild and non-irritating, and has a rich taste that leaves a lasting impression. The e-liquid of this invention comprises a refreshing extract, tobacco flavoring, tobacco leaf extract, snail flavoring, medicinal flavoring agent, agar, glycerin, and olive oil. This e-liquid uses agar and olive oil as flavor-locking agents, which not only preserves the snail flavor for a long time but also provides a subtle, refreshing plant sensation upon closer tasting, giving a sense of tranquility and relaxation, like being in nature. The addition of the medicinal flavoring agent, when mixed with the e-liquid, can relieve dizziness, headaches, and reduce swelling caused by prolonged sitting or colds. This not only preserves the flavor of e-cigarettes but also enriches the flavor options currently available on the market and reduces the health risks associated with e-cigarettes.
