Plasma-Treated Surfaces for Adhering Lyophilized Compositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid compositions do not adhere strongly to surfaces, leading to dislocation or loosening during shipment or handling, which complicates reconstitution and affects assay performance.
Innovation Solution
Plasma treatment of surfaces to increase their adhesion to solid compositions, such as lyophilized pellets, by enhancing surface hydrophilicity and wettability, thereby improving the interaction between the composition and the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solid compositions are placed on untreated surfaces, then the surface is easier to manufacture and handle, but the adhesion strength is insufficient causing dislocation during shipment and handling
Solution Approach 1:
The surface is plasma-treated in advance before the solid composition is applied. This preliminary action modifies the surface properties (increases hydrophilicity and wettability) so that when the composition is later applied and dried, it forms strong adhesion to the surface, preventing dislocation during shipment and handling.
2Reliability
If plasma treatment is applied to the surface, then adhesion strength is improved, but the manufacturing process becomes more complex
Solution Approach 1:
Plasma treatment changes the physical and chemical parameters of the surface, specifically increasing its hydrophilicity and wettability. These parameter changes enable the solid composition to adhere more reliably to the surface, preventing dislocation and ensuring complete reconstitution, thereby improving adhesion reliability.
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
Plasma-treated surfaces enhance the adhesion of solid compositions, ensuring they remain attached during processes like shipping and handling, thus maintaining the integrity of assays.
Implementation Method 1
plasma treatment of a surface can improve the adhesion to the surface of solid compositions formed by drying a liquid solution
Implementation Method 2
plasma treatment may increase the hydrophilicity of the surface and therefore its wettability, strengthening the interaction of the reagent with the surface
Implementation Method 3
drying a solution on the plasma-treated surface and forming a solid composition from the solution
Implementation Method 4
the drying comprises lyophilizing
