These biosensors detect, transmit and record information about biological substances, such as DNA and RNA, proteins, antibodies, antigens, and more.
Disease detection at an early stage is one of the biggest challenges biochemists and materials scientists are trying to meet by combining their expertise at Missouri S&T.
The researchers used nanotechnology in biomedical diagnostics – a process called nanodiagnostics – to create a new, ultrasensitive DNA biosensor.
The new sensor could potentially detect DNA-based biomarkers for early diagnosis of cancer and genetic disorders, as well as monitor patient responses to therapies.
A basic electrochemical biosensor consists of a biological recognition element, a signal converter and a processor. These biosensors detect, transmit and record information about biological substances, such as nucleic acids (DNA and RNA), proteins, antibodies, antigens, and other biological components, like glucose.
“Biosensing with nanomaterials has the advantages of greater sensitivity and faster response than traditional analytical
