Bioengineered carbon nanotube biosensor allows ultrasensitive detection of disease biomarkers

Nov 02, 2023 (Nanowerk Spotlight) The rapid detection of disease biomarkers is critical for early diagnosis and timely treatment of illnesses. However, conventional methods like immunoassays require labelling and long processing times, making point-of-care testing difficult. An emerging alternative is nanomaterial-based electronic biosensors. These devices can directly convert biological signals into measurable electrical outputs compatible with microelectronics. This enables integration of amplification, processing and display functions for rapid, accurate and quantitative…
