Improving the longevity of passive microfluidic systems through plasma polymer films with a vertical chemical gradient

Lab-on-a-chip technologies for food safety, processing, and packaging applications: a review

“…Various LOC device fabrication methods have been explored for creating different flow patterns for controlled mixing and detection. The commonly used fabrication technologies in LOC development include photolithography (Phiphatanaphiphop et al 2020 ), inkjet printing (Papamatthaiou et al 2020 ), screen printing (Sitanurak et al 2019 ), plasma oxidation (Wong et al 2020 ), and laser treatment (Grist et al 2012 ). Table 1 summarizes the chief features of various LOC device fabrication techniques and their food-related applications.…”

Fabrication of poly(PEGMA) surface with controllable thickness gradient and its mediation on the gradient adhesion of cells

“…11 A vast of surfaces with various gradients of wettability, 12 stiffness, 13 biological signals, 14 and organic-inorganic transition. 15 have been fabricated via the methods of controlled diffusion of reaction medium (liquid phase 16 and vapor 17 ), electrochemically promoted reaction by controlling the angle of inclination between electrode and target substrate, 18,19 microfluidic control, 20 microstructure patterns, 21 gradient temperature, 22 gradient exposure to UV, 23 and processive immersion. 24 Poly(ethylene glycol) (PEG) is well acknowledged as a safe macromolecule that has been frequently used as an ingredient of functional biomaterials, such as, antifouling, 25 drug-loading, 26,27 hydrogel, 28 medical adhesive 29 and biological scaffold.…”
