Abstract

An adhesive composition described herein comprises an aqueous solvent; and a population of first nano particles dispersed in the aqueous solvent, the first nano particles comprising a negative or positive charge, and an average size in three dimensions of 1 nm to 1000 nm. In some embodiments, a population of second nano particles is dispersed in the aqueous solvent, the second nano particles comprises a negative or positive charge opposite the charge of the population of first nano particles. In some embodiments, the population of first nano particles comprises an average first size in three dimensions, and the population of second nano particles comprise an average second size in three dimensions that is different from the average first size of the first nano particles.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application 62 / 566,730 filed on October 2, 2017 and U.S. Provisional Patent Application 62 / 664,739 filed on April 30, 2018. technical field [0003] The present disclosure relates to water-based adhesives, and more particularly, the present disclosure relates to water-based tissue adhesives. Background technique [0004] Traditional bioglues, especially those derived from industrial uses, e.g. based on cyanoacrylates and based on polyurethane Tissue adhesives usually undergo violent chemical reactions during use. Because of the inherent exothermic properties of chemical reactions, this type of bioglue has the risk of tissue damage. Today's research hotspot is to develop a substitute for this type of industrial adhesive, which must have the characteristics of using milder physical and chemical reactions to carry out crosslinking and tis...
