Blood test for Alzheimer’s? New sensor breakthrough gets closer

South Korean researchers have developed a method to bypass a fundamental limitation in biosensors, a step that could accelerate next-generation diagnostics for diseases such as Alzheimer’s. The study focused on overcoming the Debye screening effect in electrolyte-gated transistor, or EGT, biosensors — a phenomenon in which a cloud of charges forms around particles in a solution, effectively shielding electrical signals and reducing sensor sensitivity. EGT biosensors enable rapid, label-free dete
