“…This cyclonic plasma, which is based on two rotating discharge jets in continuous mode, is related to the reports in previous studies. [26][27][28][29] Argon gas was used as the ionization gas in this study. PSF membranes were used as samples for the cyclonic plasma tests.…”

Atmospheric-pressure plasma cyclone with argon as the carrier gas was employed to modify the polysulfone membrane to increase its surface hydrophilicity. The variation of the polysulfone surface hydrophilicity was evaluated by static contact angle measurement and it became highly hydrophilic when exposed to cyclonic plasma. The substantial rise in the surface energy of the treated polysulfone membranes as a result of surface etching and bond cleavage effect in the plasma surface modification was also observed. The chemical composition and surface morphological alteration of cyclonic plasma-treated polysulfone membranes were characterized by field-emission scanning electron microscopy and X-ray photoelectron spectroscopy. The major findings in this study showed considerably higher surface concentrations of polar functional groups for cyclonic plasma-activated polysulfone membrane surfaces. This was more than for original pristine polysulfone membrane surfaces.

“…As an example, PVDF MF membranes were modified by cyclonic atmospheric-pressure plasma (CAPP) at various operating conditions to improve intrinsic poor membrane surface properties [56]. Cernik et al showed that the electrospun membranes of PVA/natural gum karaya (GK) hydrocolloid were crosslinked with heat treatment and methane plasma was used for extraction of nanoparticles (silver, gold, platinum, CuO, and Fe3O4) from aqueous solution [57].…”

“…These radicals are responsible for initiating polymerization of monomers in the liquid or gas phase. Possible interpretation of treated plasma membranes is that it produces active sites from radicals released from CAPP; subsequently, these radicals could interrelate with the PVDF membrane to stimulate dangling bonds, extending the formation of membrane surface active sites [56]. The effect of argon/methane gas mixture plasma on PVDF membrane can possibly induces the durability and reduce the resistances of solute adsorption and cake layer on membrane surface [67].…”

“…The argon atom was affected by the amine group (NH2) of CS, which increased the energy of the surface as well as decreased the surface tension, leading to higher surface roughness that helped improve cell adhesion, allow ionic permeability, increase hydrophilicity, enhance blood absorption, and accelerate blood clotting. Even though argon could not create new functional groups, it generated free radicals and polar functional groups on the CS surface, and these free radicals reacted with the oxygen functional groups, which enhanced the hydrophilic properties and induced the fast biodegradability [11,16]. At the same time, the oxygen plasma can discharge an atomic oxygen and an OH radical; atomic oxygen mechanism is a chemical etching process for surface modification for hydrophilicity.…”

Improvement of Biological Properties of Natural Hemostatic Agent by Plasma Technology

The aim of this study was to evaluate the effect of non-thermal plasma treatment on the biological properties of a natural hemostatic agent. The results show that plasma treatment can enhance the biodegradability property of the hemostatic agent by increasing the degradation rate of the specimen up to 94.26% within 7 days. Furthermore, the plasma-treated specimen also exhibited good biocompatibility based on the cell viability test of the fibroblast cells. The cell growth and cell proliferation on this sample were found to be helpful for the wound healing process. With appropriate degradable and biocompatible properties, this modified agent could be beneficial for better control over bleeding during surgery. Research on the physical and mechanical properties are on to develop novel hemostatic products to match the requirements as far as biomedical applications are concerned., 0 (2018) MATEC Web of Conferences
