“…This versatility is attributed to the wide spectrum of physical and chemical properties, ease of fabrication with a wide variety of structures that range from simple mats to complex shapes, and biocompatibility. There are many biomedical applications utilizing polymers, for instance, drug delivery vehicles [ 58 , 59 ], tissue engineering scaffolds [ 60 , 61 ], wound dressing [ 62 , 63 , 64 ], and biomedical sensors [ 65 , 66 ]. Although polymers have suitable bulk properties for some biomedical applications, their surface properties are not appropriate.…”

Atmospheric plasma treatment is an effective and economical surface treatment technique. The main advantage of this technique is that the bulk properties of the material remain unchanged while the surface properties and biocompatibility are enhanced. Polymers are used in many biomedical applications; such as implants, because of their variable bulk properties. On the other hand, their surface properties are inadequate which demands certain surface treatments including atmospheric pressure plasma treatment. In biomedical applications, surface treatment is important to promote good cell adhesion, proliferation, and growth. This article aim is to give an overview of different atmospheric pressure plasma treatments of polymer surface, and their influence on cell-material interaction with different cell lines.

“…Однак, володіючи широким спектром фізичних і хімічних властивостей, ПАн є крихким -порошкоподібним полімером і в багатьох випадках для застосування, його наносять на різні матриціносії неорганічної та органічної полімерної природи. Важливим природним полімером, який успішно використовують для матриць-носіїв ПАн, є целюлоза (Цел) [10][11][12][13][14][15]. Відомо, що Цел волокнистий полімер і має значний попит для створення композитних матеріалів завдяки високій спорідненості до різних речовин, хімічним і механічним властивостям [16].…”

“…Найпоширеніший методо синтезу поліаніліну [1][2][3][4] і композитних матеріалів на основі поліаніліну та целюлози (Цел/ПАн) є хімічне окиснення аніліну (Ан) різними окисниками головно в водних розчинах різних кислот за наявності целюлози [10][11][12][13][14][15][16][17][18]. У процесі синтезу утворюються доповані поліанілінові шари на поверхні мікро-та нанофібрил Цел.…”

“…These 3-D polymeric structures are normally constructed by crosslinking hydrophilic polymeric chains [ 26 , 27 , 28 , 29 ]. Depending on the polymeric composition, hydrogels can be categorized into natural, synthetic and hybrid hydrogels [ 30 , 31 , 32 , 33 , 34 ]. While the latter two types are normally associated with low biocompatibility in vitro and in vivo [ 35 , 36 ], batch variations, limited functionality and potential immunogenic effects limit the applications of the natural types of hydrogels [ 30 , 37 , 38 ].…”

Herein we report the synthesis and characterization of electro-conductive chitosan–gelatin–agar (Cs-Gel-Agar) based PEDOT: PSS hydrogels for tissue engineering. Cs-Gel-Agar porous hydrogels with 0–2.0% (v/v) PEDOT: PSS were fabricated using a thermal reverse casting method where low melting agarose served as the pore template. Sample characterizations were performed by means of scanning electron microscopy (SEM), attenuated total reflectance–Fourier transform infrared spectroscopy (ATR–FTIR), X-ray diffraction analysis (XRD) and electrochemical impedance spectroscopy (EIS). Our results showed enhanced electrical conductivity of the cs-gel-agar hydrogels when mixed with DMSO-doped PEDOT: PSS wherein the optimum mixing ratio was observed at 1% (v/v) with a conductivity value of 3.35 × 10−4 S cm−1. However, increasing the PEDOT: PSS content up to 1.5 % (v/v) resulted in reduced conductivity to 3.28 × 10−4 S cm−1. We conducted in vitro stability tests on the porous hydrogels using phosphate-buffered saline (PBS) solution and investigated the hydrogels’ performances through physical observations and ATR–FTIR characterization. The present study provides promising preliminary data on the potential use of Cs-Gel-Agar-based PEDOT: PSS hydrogel for tissue engineering, and these, hence, warrant further investigation to assess their capability as biocompatible scaffolds.
