4 papersThis review compares organic bioelectronic transistors (EGOFETs and OECTs) to traditional electrochemical sensors for detecting biological molecules. It argues that organic transistors, by utilizing capacitive coupling and possibly current amplification, could offer greater sensitivity than electrochemical sensors, potentially enabling detection down to the zeptomolar range for certain analytes.
This paper reviews various sensing technologies for monitoring soil moisture and nutrients in agriculture, ranging from laboratory methods to in-situ, remote, and proximal sensing. It covers the working principles of each method and discusses recent advancements and challenges, highlighting the trend towards low-cost, field-deployable systems for precision agriculture.
Researchers developed a highly sensitive ion detector using a complementary organic electrochemical transistor (OECT) amplifier. This device can detect ion concentrations across five orders of magnitude and monitor tiny variations in real-time, exceeding the performance of current ion sensors and potentially revolutionizing biomedical diagnostics and other fields.
Researchers developed large-area graphene field-effect transistor (ISFET) arrays capable of simultaneously measuring the concentrations of multiple ions in real time with high resolution. The sensor array successfully tracked ion uptake by duckweed in an aquarium, demonstrating its potential for real-world applications like environmental monitoring.
