Güven, Melek Naz; Demirci, Gözde; Altuncu, Seçkin; Gülyüz, Ümit; Okay, Oğuz; Acar, Havva Yağcı; Avcı, Duygu (Elsevier Sci Ltd, 2020)Novel bisphosphonic acid-functionalized poly(amido amine) (PAA) macromers were synthesized through aza-Michael addition of sodium alendronate (ALE) and 5-amino-1-pentanol (AP) to N,N'-methylene bisacrylamide at two different ... -
Bisphosphonic Acid-Functionalized Cross-Linkers to Tailor Hydrogel Properties for Biomedical Applications
Güven, Melek Naz; Altuncu, Merve S.; Bal, Tuğba; Oran, Dilem C.; Gülyüz, Ümit; Kızılel, Seda; Avcı, Duygu (Amer Chemical Soc, 2018)Two bisphosphonic acid-functionalized cross-linkers (one novel) with different spacer chain characteristics were synthesized and incorporated into hydrogels by copolymerization with 2-hydroxyethyl methacrylate at different ... -
Dual Cross-Linked Polymethacrylic Acid Hydrogels with Tunable Mechanical Properties and Shape Memory Behavior
Gülyüz, Ümit (Wiley-V C H Verlag Gmbh, 2021)Herein, a series of poly(methacrylic acid) hydrogels are prepared via bulk polymerization of methacrylic acid (MAAc) and grafting of Triton X-100 (TX-100). One-pot and extremely simple chemistry consist of only mixing and ... -
Interfacing Soft and Hard Materials with Triple-Shape-Memory and Self-Healing Functions
Argun, Aslıhan; Gülyüz, Ümit; Okay, Oğuz (Amer Chemical Soc, 2018)Many natural materials such as intervertebral disk (IVD) are composed of regions with large mismatches in the mechanical properties, yet these regions are integrated through an extremely tough interface. To mimic the ... -
Micelle Crosslinked Polyacrylic Acid Hydrogels with Resilience and Self-Recovery Properties
Gülyüz, Ümit (Wiley-V C H Verlag Gmbh, 2021)Micelle crosslinking method is one of the several techniques to fabricate hydrogels with good mechanical performance. Micelle crosslinked hydrogels reported so far are fabricated using a multistep preparation process due ... -
One-Step Injectable and Bioreducible Poly(beta-Amino Ester) Hydrogels as Controlled Drug Delivery Platforms
Bingöl, Betül; Altuncu, Seçkin; Duman, Fatma Demir; Ak, Ayşe; Gülyüz, Ümit; Acar, Havva Yağcı; Avcı, Duygu (Amer Chemical Soc, 2019)A one-step synthesis strategy based on aza-Michael reaction of poly(ethylene glycol) diacrylate (PEGDA) or PEGDA/1,6-hexanediol diacrylate (HDDA) mixture and cystamine was employed to fabricate injectable, biocompatible, ... -
Semi-Crystalline, Three-Segmented Hybrid Gels with Multiple Shape-Memory Effect
Argun, Aslıhan; Gülyüz, Ümit; Okay, Oğuz (Wiley-V C H Verlag Gmbh, 2019)Natural biological systems such as intervertebral disk, tendon, and ligament consist of regions with distinctly different mechanical properties, yet these regions intermesh with each other through an extremely tough ... -
Structure-property relationships of novel phosphonate-functionalized networks and gels of poly(beta-amino esters)
Altuncu, Seçkin; Duman, Fatma Demir; Gülyüz, Ümit; Acar, Havva Yağcı; Okay, Oğuz; Avcı, Duygu (Pergamon-Elsevier Science Ltd, 2019)pH sensitivity, biodegradability and high biocompatibility make poly(beta-amino esters) (PBAEs) important biomaterials with many potential applications including drug and gene delivery and tissue engineering, where their ...
