In vivo polydopamine coating of Rhodobacter sphaeroides for enhanced electron transfer
Ardemis Anoush Boghossian, Melania Reggente, Fabian Fischer
Recent advances in coupling light-harvesting microorganisms with electronic components have led to a new generation of biohybrid devices based on microbial photocatalysts. These devices are limited by the poorly conductive interface between phototrophs and ...
2024Radiation Patterns of RF Wireless Devices Implanted in Small Animals: Unexpected Deformations Due to Body Resonance
Anja Skrivervik, Stéphanie Lacour, Zvonimir Sipus, Mingxiang Gao, German Augusto Ramirez Arroyave, Kangling Wu
One challenge in designing RF wireless bioelectronic devices is the impact of the interaction between electromagnetic waves and host body tissues on far-field wireless performance. In this paper, we investigate a peculiar phenomenon of implantable RF wirel ...
2023A guide to preclinical evaluation of hydrogel-based devices for treatment of cartilage lesions
Dominique Pioletti, Peyman Karami, Theofanis Stampoultzis, Yanheng Guo
The drive to develop cartilage implants for the treatment of major defects in the musculoskeletal sys-tem has resulted in a major research thrust towards developing biomaterial devices for cartilage repair. Investigational devices for the restoration of ar ...
ELSEVIER SCI LTD2023Prevention of the foreign body response to implantable medical devices by inflammasome inhibition
Fibrotic scarring secondary to the foreign body reaction (FBR) generates a physical barrier obstructing the functional interaction of implantable medical devices with the host tissue. The mechanistic basis of the FBR is poorly understood, restricting the c ...

2021Soft Hydrogel Zwitterionic Coatings Minimize Fibroblast and Macrophage Adhesion on Polyimide Substrates
Silvestro Micera, Anna Zahoranova, igor lacik
Minimizing the foreign body reaction to polyimide-based implanted devices plays a pivotal role in several biomedical applications. In this work, we propose materials exhibiting nonbiofouling properties and a Young's modulus reflecting that of soft human ti ...
AMER CHEMICAL SOC2019Programmable microencapsulation for enhanced mesenchymal stem cell persistence and immunomodulation
Berna Ayse Özkale Edelmann, Christina Myra Tringides
Mesenchymal stem cell (MSC) therapies demonstrate particular promise in ameliorating diseases of immune dysregulation but are hampered by short in vivo cell persistence and inconsistencies in phenotype. Here, we demonstrate that biomaterial encapsulation i ...
NATL ACAD SCIENCES2019Development of functionalized alginate-based hydrogels to reduce fibrosis in the transplantation of microencapsulated cells
Nowadays, the development of cell therapy relies mainly on the advances made toward cell microencapsulation which allows to evade the need for immunosuppression during cell transplantation. Among the materials considered for cell encapsulation, hydrogels d ...
