Congratulations to former visiting scientist Sun Kim on the upcoming publication of our collaborative work on wound healing mediated by exosome release from hydrogels
While Dr. Kim was a visiting scientist in Berkeley, we collaborated to develop a hydrogel release system for exosomes. In this paper, exosomes derived from M2-macrophages (M2-Mφs), which contain putative key regulators driving Mφ polarization, were used as local microenvironmental cues to induce reprogramming of M1-Mφs toward M2-Mφs for effective wound management. As an injectable …
Congratulations to former group members Peyman and Brylee on the publication of their collaborative work with George Degen on mussel-inspired PSAs
Peyman and Brylee collaborated with George to explore the effects of catechol content, molecular architecture, and solvent quality on mussel-inspired pressure-sensitive adhesive (PSA) adhesion and cohesion measured in a surface forces apparatus. Their findings demonstrate that the influence of catechol content depends on the choice of solvent and that adhesive performance is dictated by film …
Congratulations to Kelsey on the recent publication of her paper on oxygen sensing pathways and tissue regeneration.
Kelsey’s paper with Ellen Heber-Katz was published in Biomaterials.The paper reviews ancient oxygen-sensing pathways as a possible target to achieve tissue regeneration. Specifically, upregulation of the transcription factor, hypoxia-inducible factor one alpha (HIF-1α) has been shown to modulate cell metabolism and plasticity, as well as inflammation and tissue remodeling, possibly priming injuries for regeneration. Since …
Congratulations to Katerina on the publication of her collaboration with the Hartwig group on enhanced adhesion to polyethylene via catalytic oxidation of C-H bonds
Katerina collaborated with Liye Chen of the Hartwig group on their study of catalytic oxidation of polyethylene. This paper reports the selective oxidation of polyethylenes to incorporate functional groups that imbue physical properties unseen in the unmodified materials. Although further work is needed to create catalysts that reach commercially suitable lifetimes with sustainable oxidants to …
Conversations on Bioinspired Engineering Webinar
We are pleased to announce a free international webinar series featuring invited scientific talks from graduate students and postdocs on topics relevant to bioinspired engineering and biomedicine. In a time that the mission of science has never been more pertinent, this webinar series is an initiative to bring cutting edge research directly to you and …
Congratulations to Dirk, Sally and Yiran on publication of their paper in ACS Macro Letters!
Congratulations to Diederik Balkenende, Sally Winkler, and Yiran Li on publication of their paper in ACS Macro Letters! Here we introduce a tissue-adhesive patch with orthogonal cohesive and adhesive chemistries; supramolecular ureido-4-pyrimidinone (UPy) cross-links provide cohesive strength, and catechols provide mussel-inspired tissue adhesion. We found that using orthogonal motifs to independently control adhesives’ cohesive and …
Congratulations to Kyueui, Katerina, Jisoo, Sally, and Yuting on publication of their paper in Nature Communications!
Congratulations to Kyueui Lee, Katerina Malollari, Jisoo Shin, Sally Winkler, Yuting Zheng on publication of their paper “Laser-induced graphitization of polydopamine leads to enhanced mechanical performance while preserving multifunctionality” in Nature Communications! In this work, blue diode laser-annealing is introduced to enhance mechanical stability of polydopamine through partial graphitization while preserving its multifunctionality. Moreover, surface roughness of …
