Embodiment

[0026] Example: see Figure 1-4 .

[0027] The core content of this patent is how to convert light energy into heat energy, and then stimulate the secretion of tears to prevent dry eyes. Therefore need a kind of light-to-heat conversion material, when selecting light-to-heat conversion material, find that under the same temperature and chemical physical environment conditions, the palladium clad gold nanorod has higher energy efficiency than the pure palladium nanorod or the pure gold nanorod of the same dosage. light-to-heat conversion efficiency. Therefore, we choose gold nanorods@palladium (GNRs@Pd) as the photothermal conversion material, which is also the core material of this eye patch. Put this eye patch on the lacrimal gland, it can sense all kinds of light, then heat, and then Stimulates the secretions of the lacrimal glands to relieve dry eyes. In addition, the built-in temperature-sensitive ink can change color with the temperature of the eye stickers, which can ...

Abstract

The invention relates to the technical field of multifunctional nanomaterials, in particular to a preparation method of an intelligent eye patch for relieving dry eye symptoms. A preparation method of an intelligent eye patch for relieving dry eye symptoms, comprising the steps of: first preparing palladium-coated gold nanorods, and then configuring gelatin and A-d solution into a gelatin A-d solution with a mass fraction of 30% , and stir to form a solution under 40-50 degree water bath conditions; ensure that the volume ratio of 1% genipin solution to B-a solution is 1:20, take 1% genipin solution in solution B-a, and stir evenly ; Draw an appropriate amount of solution B‑b into the 3D printed special mold, and drop 2‑3 drops of 20% FeCl on the surface 3 solution. Let stand for a day, and then take out the formed eye patch from the mold after molding; open the hole in the formed eye patch, and insert the temperature-sensitive material into the formed eye patch hole. The smart eye patch prepared by the invention is sensitive to heat, stimulates tear secretion, relieves dry eye, does not interfere with normal eye use, can be customized, and is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of multifunctional nanomaterials, in particular to a preparation method of an intelligent eye patch for alleviating dry eye symptoms. Background technique [0002] With the popularity of video terminals, the incidence of dry eye is increasing year by year. Its treatment has also emerged as a major concern in ophthalmology. Currently, the most important treatment for dry eye is tear replacement therapy, the topical use of artificial tears to improve ocular surface moisture and lubrication. However, since the tears secreted by the human body are complex and contain water, electrolytes, proteins, lipids, etc., it is difficult for artificial tears to be completely the same as natural tears. In addition, many commercially available artificial tears contain preservatives, although the concentration is very low, but their damage to eye cells cannot be ignored. At present, infrared health eye masks for the treatm...
