Hydrogels that dry during the reading, rough graphene electrodes, paper channels that leak and chips whose plasma treatment faded all give misleading numbers or failed devices. Contact angle and interfacial tension, measured with a method fixed for the material, catch drift before devices are built. Used in biomaterials, flexible electronics, diagnostics, microfluidics and oil recovery.
Use cases showing how contact angle and interfacial tension measure wetting and wicking on hydrogels, graphene electrodes, paper and polymer microfluidics, and chemically treated surfaces.
Hydrogel and Biomaterial Wettability for Tissue Engineering
Measures hydrogel and scaffold contact angle with fixed swelling, blotting and read time, so drying and absorption do not decide the number.
LIG Flexible Electronics Electrode QC
Checks each laser induced graphene batch with a contact angle fit built for rough surfaces, catching process drift before sensors are built.
Paper Microfluidic and Lateral Flow Wicking Control
Checks barrier and channel wetting on paper devices before and after each fabrication change, then confirms the result with a leak or flow test.
Polymer Microfluidic Channel Wettability
Tracks PDMS and thermoplastic chip wetting on matched coupons after plasma or coating and again at use, so faded treatments are caught before filling.
Wettability Alteration Screening (Surfactant and Chemical)
Ranks surfactants and chemicals by how far they move aged plates toward water wet and how much they lower interfacial tension, before core tests.
