Novel biosensing devices, like bio-FET sensors, offer label-free analysis by detecting ionic and biomolecular charges, crucial for diagnostics and biological research.

Explore the eco-friendly potential of organic thin film transistors (OTFTs) for detecting chemical analytes, identifying viruses, and assisting in health diagnostics. This mini-review highlights challenges of achieving sustainability, safety, and biodegradability of each component of an OTFT sensor.

Professor Chen (Nankai University, China) and his team explain the strategies behind their recent record-breaking organic solar cells, reaching a power conversion efficiency of 17.3%.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
