Surface characteristics of UV-irradiated collagen/PVP blended films

Surface properties of UV-irradiated poly(vinyl alcohol) films containing small amount of collagen

“…Surface properties can be modified by many factors, like UV-irradiation, laser treatment, mechanical treatment and heating [4][5][6]. The surface properties of man-made polymers can be modified also by the addition of other polymer and/or biopolymer [7][8][9][10]. For instance the surface properties of poly(-vinyl pyrrolidone) films can be modified by the addition of biopolymers like collagen [7,8] and chitosan [9].…”

Stabilization of type I collagen against collagenases (type I) and thermal degradation using iron complex

“…The thermally induced structural transitions in the fibrous collagenous network lead to shrinkage process [11]. The effect of physical parameters like UV radiation on the thermal properties of collagen has been studied extensively [12][13][14][15]. Collagen is actively digested by a class of metalloproteinases known as collagenases [16].…”

Photochemical stability of poly(vinyl pyrrolidone) in the presence of collagen

“…The blends of collagen with PVP have been studied by our research group previously [16][17][18][19][20]. In our previous studies we have shown that collagen and PVP are miscible [16].…”
