Antimicrobial Silane Coating for Lasting Surface Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disposable wipes effectively kill bacteria on contact but fail to prevent subsequent bacterial collection on treated surfaces, as they do not provide a lasting antimicrobial treatment.
Innovation Solution
An antimicrobial wipe solution comprising unreacted organofunctional silane antimicrobial treatment substance, free from arsenic, silver, tin, heavy metals, and polychlorinated phenols, combined with isopropyl alcohol, which permanently bonds to surfaces to create a protective coating that destroys microbes and prevents future contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional disposable wipes with disinfecting solution are used, then bacteria are killed on contact, but bacteria subsequently collect on the surface again
Solution Approach 1:
The wipe is pre-treated with unreacted organofunctional silane that will react with the surface upon application, creating a permanent antimicrobial coating before bacterial recolonization can occur
Solution Approach 2:
The patent changes the chemical state of the silane from reacted (inactive) to unreacted (active), enabling it to bond with surfaces and provide lasting protection rather than temporary disinfection
2Ease of manufacture
If organosilicon antimicrobial substance is reacted before application, then the wipe can be manufactured, but it cannot treat surfaces permanently
Solution Approach 1:
The silane is applied in unreacted form during manufacturing, allowing easy incorporation into the wipe, then reacts with the target surface during use to create permanent bonding and lasting antimicrobial effect
Solution Approach 2:
The unreacted silane acts as an intermediary that transfers from the wipe to the surface, bonding to both the wipe substrate and the target surface to create a permanent antimicrobial bridge
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides long-lasting antimicrobial protection, lasting at least one week and potentially indefinitely, preventing microbial growth and odor, while remaining effective against a broad spectrum of microorganisms without being removed by conventional cleaners.
Implementation Method 1
an unreacted organofunctional silane antimicrobial treatment substance that is substantially free from arsenic, silver, tin, heavy metals and polychlorinated phenols

AI summary
A surface of an object may be treated using an antimicrobial wipe presoaked in an antimicrobial treatment solution. Alternatively, the antimicrobial treatment solution may be sprayed directly on the surface. The antimicrobial treatment solution may be made of isopropyl alcohol and an unreacted organofunctional silane antimicrobial substance that is substantially free from arsenic, silver, tin, heavy metals and polychlorinated phenols. The antimicrobial substance may include any one of: 3 trimethoxysilylpropyloctadecyldimethyl ammonium chloride; hyaluronan and its derivatives; triclosan; and a copolymer of chloropropyltrihydroxysilane and octadecylaminodimethyltrihydroxysilylpropyl ammonium chloride.
