Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting enzymatic activity towards polymers are complex, require large quantities of material, and are not suitable for testing multiple polymers or enzymes simultaneously, often necessitating expensive equipment and advanced expertise.
Innovation Solution
A method involving micro-deposits of lenticular shape made from polymers or polymer mixtures, which are exposed to a compound, allowing detection of changes in light intensity due to variations in dimensions or refractive index, enabling visual or quantitative assessment of enzymatic degradation without the need for extensive reagents or specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If interferometry with thin transparent polymer films is used to detect enzymatic activity, then sensitivity is improved (125 to 1,000 times lower threshold than classical methods), but material loss increases significantly (over 90% loss during centrifugal coating)
Solution Approach 1:
The patent divides the continuous thin film into discrete micro-deposits (microlenses) arranged in arrays on the support. Each micro-deposit is a localized polymer structure that can be individually tested, eliminating the need to coat the entire support surface and reducing material consumption while maintaining optical interference functionality.
Solution Approach 2:
The patent creates localized polymer structures (micro-deposits) with specific optical properties at discrete locations on the support rather than uniform coating. Each micro-deposit has controlled dimensions and refractive index properties optimized for light interference, achieving high detection sensitivity with minimal material usage.
2Stability of the object's composition
If centrifugal coating is used to deposit polymer films on supports, then continuous film coverage is achieved, but material loss exceeds 90%
Solution Approach 1:
The patent replaces continuous film coating with discrete micro-deposit formation. Micro-deposits are deposited at specific locations using techniques such as inkjet printing or microcontact printing, eliminating the waste inherent in centrifugal coating while maintaining sufficient polymer coverage for optical detection.
3Measurement precision
If multi-well plate format with modified substrates is used for enzyme assays, then enzymatic activity detection is enabled, but material volumes required are large (microliters) and equipment complexity increases
Solution Approach 1:
The patent transitions from bulk material consumption in multi-well plates to surface-based micro-deposit arrays. By arranging multiple micro-deposits on a single support, the system enables parallel testing of multiple enzymes or polymers simultaneously using minimal material volumes, reducing both material consumption and equipment requirements.
4Device complexity
If a single polymer is spread per support in interferometry, then simple device structure is maintained, but versatility to test multiple polymers or enzymes is limited
Solution Approach 1:
The patent creates an array of micro-deposits on a single support, where each micro-deposit can contain different polymers or be exposed to different enzymes. This segmented approach allows simultaneous testing of multiple polymer-enzyme combinations while maintaining a simple single-support device structure.
Solution Approach 2:
The patent designs the support with arrays of micro-deposits that can serve multiple functions: different micro-deposits can test different polymers, different enzymes, or different conditions simultaneously. This multi-functional design increases versatility without requiring multiple separate devices.

AI summary
The present invention relates to a method for detecting the sensitivity of one or more polymers and/or one or more polymer blends to a compound, comprising the steps of: exposing at least one lens-shaped micro-deposit (21) comprising the polymer(s) and/or polymer blend(s) to the compound; and illuminating the surface of the micro-deposit in order to detect a change in the spatial distribution of the intensity of the light reflected or transmitted by the micro-deposit, linked to a variation in the dimensions and/or the refractive index of the micro-deposit, as a result of an interaction between the polymer(s) and/or polymer blend(s) and the compound.
