Plasma aminofunctionalisation of PVDF microfiltration membranes: comparison of the in plasma modifications with a grafting method using ESCA and an amino-selective fluorescent probe

Incorporation of Primary Amines via Plasma Technology on Biomaterials

“…This was also observed by Lejeune et al and Müller et al [57,69]. The effect of plasma on the retention of the precursor functional group also depends on the plasma mode.…”

Functionalization of Biomedical Polymers by Means of Plasma Processes: Plasma Treated Polymers with Limited Hydrophobic Recovery and PE-CVD of -COOH Functional Coatings.

“…Micro-patterning biomedical surfaces by plasma Cells are sensible to topographic and chemical features of sub-micrometric dimensions [16,18]; random and geometrical micro-and nano-metric patterns transferred at the surface of biomedical polymers are known for their ability, in certain contests, of driving the adhesion, motion, spreading and growth steps of cells at their surface. This effect, known as "contact guidance", is quite far, yet, from being completely understood, but could be utilized in a number of fundamental studies and practical applications for biosensors, diagnostic kits and tissue engineering [13][14][15][16][17][18]. Experiments in this last field, for example, include the use of surface-patterned biodegradable polymers as scaffolds for cell cultures.…”

“…), with lateral dimensions of a few micron at the lowest, can be developed at the surface of polymers by means of plasma processes performed through "physical masks", i, e., micronthick polymer or metal foils, where holes of proper size and shape are precisely drilled, e.g., by laser techniques. When properly positioned at the surface of the polymer under modification, and utilized with selected plasma processes, physical masks allow to transfer their pattern, with the best reported resolution of a few microns [13][14][15].…”

“…Since quite recently, combined PE-CVD, treatment and etching processes are utilized also to transfer geometric micrometric patterns at the surface of biomedical polymers [13][14][15], with the aim of driving the behaviour of cells (contact guidance [16][17][18]), for example in tissue engineering.…”

Preparation and characterization of Protein A-immobilized PVDF and PES membranes

“…As such, PVDF and PES membranes are important candidates as affinity media. Plasma processing is a dry process for clean and energy saving surface modifications [16,17]. Compared to plasma processing with a vacuum, atmospheric pressure low-temperature plasma does not need equipment for vacuum processing [18].…”
