Article Synopsis
- Zika virus (ZIKV) and dengue virus (DENV) are dangerous diseases spread by mosquitoes, with their infection rates expected to rise due to global warming, emphasizing the need for better diagnostic methods.
- Research is focusing on biosensors utilizing DNA nanotechnology as a more efficient alternative to traditional diagnostic techniques like PCR and ELISA, allowing for more accurate detection of these viruses.
- The review highlights various technologies—electrochemical, electrical, and optical—that are being developed using DNA nanotechnology to enhance the detection of ZIKV and DENV through innovative bioreceptors that target viral components directly.
A novel biomimicked neuromorphic sensor for an energy efficient and highly scalable electronic tongue (E-tongue) is demonstrated with a metal-oxide-semiconductor field-effect transistor (MOSFET). By mimicking a biological gustatory neuron, the proposed E-tongue can simultaneously detect ion concentrations of chemicals on an extended gate and encode spike signals on the MOSFET, which acts as an input neuron in a spiking neural network (SNN). Such in-sensor neuromorphic functioning can reduce the energy and area consumption of the conventional E-tongue hardware.
