Bio-hybrid blended transparent and conductive films PEDOT:PSS:Chitosan exhibiting electro-active and antibacterial properties

Facile synthesis of highly conductive PEDOT:PSS via surfactant templates

“…55 The broad bands between 600 and 900 nm and between 700 to 1000 nm can be ascribed to the polaron and bipolaron states of PEDOT:PSS, respectively, indicative of the characteristic doped state of PEDOT:PSS. 25 For the effects of EDOT : PSS weight ratio and EDOT : Na 2 -S 2 O 8 mole ratio, the characteristics of the PEDOT:PSS UVspectra were nearly the same with an increase in EDOT : PSS weight ratio or increase in EDOT : Na 2 S 2 O 8 mole ratio, consistent with previous work of Khan and Narula, 2016. 25 3.4.2 Band gap energy.…”

The band gap energy of PEDOT:PSS was calculated by using the Tauc relation (eqn (1)), as tabulated in Table 2.…”

Antibacterial poly (3,4-ethylenedioxythiophene):poly(styrene-sulfonate)/agarose nanocomposite hydrogels with thermo-processability and self-healing

“…cm -1 corresponding to -OH and -C-O-Cgroups of agarose, respectively, were shifted towards lower wavenumber values in composite gel, indicating that there is hydrogen-bonding interaction between agarose and -SO3H group on PSS of PEDOT:PSS (Hu et al, 2016;Kadla & Kubo, 2003;Khan et al, 2016;Kuo & Chang, 2001). Figure 1D).…”

“…In this study, the goal of this study is to present an antibacterial all-organic nanocomposite hydrogel composed of poly(3,4-ethylenedioxythiophene) poly(styrene-sulfonate) (PEDOT:PSS) and agarose with thermo-processability and self-healing ability. PEDOT:PSS, an aqueous-based conductive polymer nanoparticles with strong NIR absorbance, has recently emerged as a new NIR photothermal therapy (PTT) agent due to its water-dispersibility, high photothermal conversion efficiency, excellent photostability, and good biocompatibility (Jeong et al, 2015;Khan & Narula, 2016;You et al, 2013). Agarose, one of the main polysaccharide components of agar, serves as the hydrogel backbone for antibacterial nanocomposite hydrogels.…”

Inherent antibacterial activity and in vitro biocompatibility of hydrophilic polymer film containing chemically anchored sulfadiazine moieties

“…This is especially concerning when it comes to implant surgery and medical devices where there has to be a balance between antibacterial properties and biocompatibility [3]. Extensive research has been conducted on antibacterial properties of materials [2,4,5]. However the threat of emerging and widespread bacterial resistance to antibiotics [6] which are by far the most commonly used antimicrobial pharmaceutical agents, is endangering their efficacy [7].…”
