“…This was attributed to the presence of active groups in plasma, such as UV, electrons, and radicals. Many previous studies have reported that UV exposure could lead to gelatin intermolecular crosslinking 26) and, possibly, to the formation of radicals on the aromatic amino acids, such as tyrosine and phenylalanine, in collagen and gelatin 27,28) . The electrons of plasma may interact with polymers to induce the formation of radicals in the polymeric collagen fibers to promote crosslinking 29) .…”

The radio-frequency atmospheric-pressure glow discharge (RF-APGD) plasma is a novel cold atmospheric plasma (CAP) source, which has low energy characteristic. This study investigated the effect of RF-APGD plasma on the mechanical properties of dentin collagen and resin-dentin bonding. The scanning electron microscopy analysis was performed before and after a novel RF-APGD plasma and a conventional CAP treatment and a tensile test was carried out for the stiffness of dentin collagen. The microtensile resin-dentin bond strength was tested either immediately or after a 50,000-cycle thermocycling process. Dentin collagen maintained an intact structure after a 45-s RF-APGD plasma treatment, whereas even a 10-s treatment with the conventional CAP collapsed the collagen scaffold. When compared with control groups, the RF-APGD plasma treatment showed: (i) an improved stiffness of dentin collagen; (ii) a significant improvement in the bonding strength before/after artificial aging. Thus, RF-APGD plasma treatment has excellent prospects as a resin-dentin bonding protocol.

“…The gelatin fiber mats in group #2 were crosslinked by pulsed inductively coupled plasma (PICP) treatment under argon gas (Ar) at a pressure of 5 Pa and for 1 pulse (PLAS). The details of PICP treatment were reported elsewhere [16,17]. Group #3 was the DHT treated gelatin fiber mats that were further crosslinked via PICP technique at the same conditions described for group #2 (DHT/PLAS).…”

“…The crosslinking depth depended on the treatment time, and plasma power, with the maximum being found to be ≈160 µm . In our previous study, pulsed inductively coupled plasmas (PICP) were applied to induce the crosslinking of gelatin films . The crosslinking degree was, however, very low compared to the that achieved by conventional de‐hydrothermal technique.…”

This study uses discharges in solutions for the treatment of gelatin solutions in order to generate crosslinking. The effects of plasma on the properties of gelatin solutions were investigated, the latter including viscosity, amino acid contents, chemical analyses, and gel strengths. The results show that, after short duration plasma treatments (5–10 min), the viscosity of the gelatin solutions increased, while the concentration of OH· free radicals decreased. After adding ethanol to the gelatin solutions, a greater increase in viscosity, and a greater decrease in free radicals were found. This suggests that ethanol provides more free radicals that can promote the crosslinking of the gelatin solution during the plasma treatment, resulting in higher viscosity. The gel strength of the gelatin was greatly enhanced by the plasma treatment of the solution. The results regarding the free amino acid contents showed that the crosslinking degree of plasma‐treated gelatin was higher than that of the untreated gelatin. FTIR measurements show that after plasma treatment, the IR bands at 1 668 and 1 558 cm−1, corresponding to the amide I and II groups of gelatin, shifted to higher wavenumbers, i.e. 1 672 and 1 564 cm−1, respectively. This suggests that crosslinking has occurred between gelatin molecules. The results show that discharges in solutions may be able to induce crosslinking reactions in the gelatin. Electrical discharges in solutions can be chemical‐free, alternative crosslinking methods.
