2D MXenes exhibit a range of interesting properties that make them suitable for healthcare-related applications. These include efficient electronic and ionic charge transport, hydrophilicity, redox activity, biocompatibility, antimicrobial effects, vis-NIR plasmon resonance, photothermal effect (light to heat conversion), tunable surface terminal groups, and structural and chemical tunability. In addition, MXenes can be synthesized using solution processing in water providing a simple method for low-cost processing of 2D flakes, thin and thick films, aerogels, and hydrogels at scale. Recently, the applications of MXene in healthcare and biomedical applications have seen tremendous activity covering areas such as biosensing, electrophysiology, tissue engineering, antimicrobial and antiviral treatments, and therapeutics.
In this talk, I will discuss the use of MXenes in several devices for biomedical applications. This includes using MXene-based hydrogels as physical and electromechanical sensors (e.g., physical motion, body artifacts, muscle fatigue) including wearable and stand-alone sensors. The talk will also cover using MXene-based composites as wearable sweat sensors with a unique modular design that enabled a simple exchange of the specific sensing electrode to tailor to the desired analytes to detect multiple biomarkers in sweat. The talk also includes leveraging the ability of MXene hydrogels to absorb ultrasound energy to develop an implantable battery that can be charged remotely from medical ultrasound probes. Promising new directions for MXenes and related composition will be discussed.
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.
