Dr. Aruã C. Da Silva completed a technical-vocational course in Chemistry at the State Center for Technological Education Paula Souza (2009) and holds a B.Sc. in Chemistry from the State University of Londrina (2013). He served as a Visiting Researcher at the University of Wollongong, Australia (2017–2018), and earned his Ph.D. in Science from the University of São Paulo (2020), awarded for its quality in 2021. From 2020 to 2024, he worked as an Associate Researcher on Implantable Bioelectronic Systems at the University of Sheffield. Currently, he is a Research Fellow at the University of Limerick, Ireland, focusing on the development of a hydrogel-based sealant system for in vivo applications. For more details at:

My research lies at the interface of biomaterials, electrochemistry, and biomedical engineering, with a particular focus on the design and characterization of hydrogel-based systems for clinical and bioelectronic applications. I am especially interested in developing biocompatible, biodegradable, and electroactive hydrogels that can serve as functional interfaces between soft biological tissues and electronic devices, enabling next-generation solutions in drug delivery, regenerative medicine, and implantable medical technologies.

Currently, as a Research Fellow at the University of Limerick, I am working on the development of hydrogel-based sealant systems for in vivo applications through a collaborative project with Selio Medical, supported by the Disruptive Technologies Innovation Fund (Enterprise Ireland). My work involves establishing ex vivo testing models to evaluate hydrogel–tissue interactions in the liver and kidney, as well as optimizing biodegradable formulations for biopsy procedures. I also focus on clinical translation aspects, including degradation studies, sterilization, rheology, biocompatibility, and large-scale manufacturing of pre-filled syringe prototypes for medical use.

Previously, during my Postdoctoral Research Associate position at the University of Sheffield under an ERC Starting Grant (Integrabrain Project), I investigated conductive hydrogels for bioelectronics. My work explored electro-assisted 3D printing, bipolar electrochemistry, and electrochemical assembly methods to produce soft, conductive polymer–hydrogel hybrids. These systems aim to improve adhesion and signal transduction at soft–hard interfaces, advancing technologies for neural interfacing, biosensing, and soft bioelectronic devices.

My earlier research has contributed to a solid foundation in conducting polymer chemistry, biopolymer synthesis, and surface–protein interactions. During my PhD, I developed conducting, biodegradable copolymers based on PEDOT and PDLLA, studying their interactions with extracellular matrix proteins to support cell adhesion and tissue integration. This work was complemented by an international research internship focused on atomic force microscopy (AFM) characterization of protein–polymer interfaces, as well as earlier undergraduate projects on nanostructured materials for electrocatalysis and corrosion protection.

Overall, my research aims to bridge materials chemistry and biomedical engineering to create smart, functional materials capable of addressing clinical challenges, improving tissue repair, and enabling wireless, minimally invasive therapeutic systems.
