Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hemostatic and wound closure materials suffer from toxicity, weak adhesion, and poor mechanical strength in wet environments, and there is a need for biocompatible materials that can deliver nutrients to cells to promote cell activities such as adhesion, hemostasis, wound healing, and antibacterial activity.
Innovation Solution
Polymer nanoparticles of metabolites, formed from peptide bonds, ester bonds, or glycosyl linkages, with diameters of 300 nm or less, that permeate into cells to rapidly supply nutrients by decomposing into metabolites like glucose, fructose, or 3-hydroxybutyrate, promoting cell activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If inorganic nanoparticles are used for adhesion, then adhesion strength is improved, but cell toxicity and inflammation occur
Solution Approach 1:
The patent changes the material composition parameter from inorganic nanoparticles to polymer nanoparticles made from metabolites (such as amino acids, sugars, fatty acids). This parameter change maintains the nanoparticle size (1-100 nm) for adhesion while altering the chemical composition to be biocompatible and non-toxic, thereby resolving the contradiction between adhesion strength and cell toxicity
Solution Approach 2:
The patent uses polymer nanoparticles that are designed to be temporarily present and then decomposed by cellular enzymes into their constituent metabolites. These metabolites are then utilized by cells for energy and building blocks. The nanoparticles serve their adhesion function and then naturally degrade, avoiding long-term toxicity while maintaining effectiveness
2Reliability
If conventional tissue adhesives are used, then hemostasis and wound closure are achieved, but biocompatibility and tissue adhesion strength are insufficient
Solution Approach 1:
The patent employs composite nanoparticle formulations consisting of multiple metabolite polymers (e.g., proteins, polysaccharides, lipids) that work synergistically. These composite materials provide both the mechanical adhesion properties needed for wound closure and the biocompatibility required for tissue integration, overcoming the limitations of single-material conventional adhesives
Solution Approach 2:
The polymer nanoparticles are designed to be self-decomposing through enzymatic hydrolysis by cellular enzymes into metabolites that cells can directly utilize. This self-service mechanism eliminates the need for external removal or degradation assistance, providing both effective wound closure and excellent biocompatibility as the material becomes part of the body's natural metabolic cycle
3Strength
If nanoparticle size is reduced to enhance adhesion, then adhesion ability is improved, but cell membrane damage occurs
Solution Approach 1:
The patent optimizes the nanoparticle size parameter to the range of 1-100 nm, which is small enough to facilitate cellular uptake and adhesion but large enough to avoid the strongest electrostatic interactions that cause membrane damage. Additionally, the surface chemistry parameter is changed to use metabolite-based compositions that are inherently biocompatible, reducing harmful interactions while maintaining adhesion effectiveness
