Stabilization Polymer Layer for Microarray Probe Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microarray technology is hindered by the susceptibility of biomolecule probes to degradation during storage and transportation, leading to reduced sensitivity and increased risk of incorrect diagnosis due to artifacts, which limits their use in various applications.
Innovation Solution
A stabilization polymer layer is applied to the substrate-bound probe molecules to inhibit degradation, increasing the shelf life and stability of the probes during storage and transportation, and allowing for multiple uses with different target analyte samples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biomolecule probes are stored under ambient conditions, then ease of operation is improved, but reliability deteriorates due to degradation
Solution Approach 1:
A stabilization polymer layer is applied as an intermediary substance between the biomolecule probe and the ambient environment. This polymer layer acts as a protective mediator that prevents direct contact between degrading environmental factors (oxygen, moisture, light) and the probe molecules, thereby maintaining probe stability while allowing ambient storage conditions.
Solution Approach 2:
The invention creates a composite structure consisting of the biomolecule probe embedded within or coated by a stabilization polymer matrix. This composite material combines the functional properties of the biomolecule probe with the protective properties of the polymer, achieving both ease of operation and reliability simultaneously.
2Productivity
If probe storage time is extended, then productivity is improved through multiple uses, but reliability deteriorates due to degradation
Solution Approach 1:
The stabilization polymer layer is applied in advance before storage and multiple uses. This preliminary protective action prevents degradation from occurring during extended storage periods, enabling the probes to maintain their signal intensity and functionality across multiple uses and extended time periods.
Solution Approach 2:
The polymer stabilization layer serves as a preemptive protective barrier that cushions the probe molecules against environmental degradation factors before exposure occurs. This beforehand protection allows the probes to withstand extended storage and repeated use without losing reliability or signal intensity.
