Over the past decades, significant efforts have focused on designing structurally diverse organic semiconductors to gain control over their electronic properties and processability. This has led to substantial progress in understanding how chemical structure and optoelectronic properties influence molecular packing and device performance. As electronic devices advance from portable to wearable and implantable technologies, there is tremendous potential for applications in healthcare diagnostics. However, the interaction of organic semiconductors with biological systems remains poorly understood.
In this work, we present our latest research on integrating organic semiconductors with biological systems, focusing on the material design requirements for bioelectronic applications. We demonstrate the creation of bioelectronic scaffolds embedded with therapeutic cells for peripheral nerve repair. Our constructs maintained cell viability and significantly upregulated pro-regenerative gene expression, particularly the transcription factor c-Jun, which is critical for Schwann cell repair. These bioelectronic tissue-engineered constructs aim to enhance both the therapeutic cells and the body’s endogenous nerve repair mechanisms. By incorporating electrical stimulation (ES) into the regenerative process, our system further augments nerve repair following surgical implantation of the bioelectronic scaffold. Additionally, we explore chemical modifications of organic semiconductors to optimize polymer-cell interfaces, emphasizing their effects on cell viability and proliferation. These findings are crucial for the successful integration of organic electronics with biological systems in future bioelectronic devices.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
