Advancements and future directions in the antibacterial wound dressings - a review
Bal-Ozturk, Ayca; Ozkahraman, Bengi; Ozbas, Zehra; Yasayan, Gokcen; Tamahkar, Emel; Alarcin, Emine (2021)Wound repair is a complex process that has not been entirely understood. It can conclude in several irregularities. Hence, designing an appropriate wound dressing that can accelerate the healing period is critical. Infections, ... -
Aloe vera-based antibacterial porous sponges for wound dressing applications
Tamahkar, Emel; Ozkahraman, Bengi; Ozbas, Zehra; Izbudak, Burcin; Yarimcan, Filiz; Boran, Filiz; Bal-Ozturk, Ayca (SPRINGER, 2021)The antibacterial sponges with high macroporosity, high interconnectivity and high biocompatibility is a significant concern for wound healing applications. In this work, novel Aloe vera (AV) based sponges were developed ... -
Boric acid-impregnated silk fibroin/gelatin/hyaluronic acid-based films for improving the wound healing process
Ozen, Nurten; Ozbas, Zehra; İzbudak, Burcin; Emik, Serkan; Ozkahraman, Bengi; Bal-Ozturk, Ayca (Journal of Applied Polymer Science, 2021)Recently, with the progression in wound dressings, the importance of the biocompatible material with enhanced features for potential applications in the biomedical field has been more developed. Current strategies focus ... -
Controlled release profile of 5-fluorouracil loaded P(AAM-co-NVP-co-DEAEMA) microgel prepared via free radical precipitation polymerization
Ozbas, Zehra; Ozkahraman, Bengi; Bal-Ozturk, Ayca (Springer, 2018)A new microgel was prepared by free radical precipitation polymerization of acrylamide (AAM), 1-vinyl-2-pyrrolidone (NVP) and 2-(diethylamino)ethyl methacrylate (DEAEMA) to be used for the controlled drug release. The ... -
Development of mucoadhesive modified kappa-carrageenan/pectin patches for controlled delivery of drug in the buccal cavity
Ozkahraman, Bengi; Ozbas, Zehra; Yasayan, Gokcen; Puren Akguner, Zeynep; Yarimcan, Filiz; Alarcin, Emine; Bal-Ozturk, Ayca (Wiley, 2021)In this study, modified kappa-carrageenan/pectin hydrogel patches were fabricated for treatment of buccal fungal infections. For this purpose, kappa-carrageenan-g-acrylic acid was modified with different thiolated agents ... -
The effect of thiol functional groups on bovine serum albumin/chitosan buccal mucoadhesive patches
Bal-Ozturk, Ayca; Alarcin, Emine; Ozbas, Zehra; Ozkahraman, Bengi (Editions de Sante, 2022)In this research, the effect of thiol functional groups on bovine serum albumin (BSA)/chitosan (Chi) based buccal mucoadhesive patch was investigated. Thiolated BSA (BSA-SH) was prepared via 2-mercaptoethanol. FTIR and 1H ... -
The effect of vitamin c in the formulation of pectin/thiolated alginate buccal adhesive patches: in vitro and ex vivo evaluation
Ozkahraman, Bengi; Torkay, Gulsah; Ozbas, Zehra; Bal Ozturk, Ayca (Elsevier Ltd., 2022)The present study outlines the prospect of a pectin (Pec)/modified alginate (Alg) buccal patch as drug delivery device in the localized treatment of oral cavity diseases. Firstly, Alg was modified with acrylic acid, and ... -
Evaluation of modified pectin/alginate buccal patches with enhanced mucoadhesive properties for drug release systems: in-vitro and ex-vivo study
Ozbas, Zehra; Ozkahraman, Bengi; Akguner, Zeynep Puren; Bal Ozturk, Ayca (Editions de Sante, 2022)A recent approach for buccal mucoadhesive system is the production of thiolated polymers via thiomer. In this study, pectin was grafted with acrylic acid before the thiolation by L-cystein and it was characterized by FTIR, ... -
