Biosensors and Bioelectronics

The costliness of drug development and the limitations of studying physiological processes in the lab are two separate scientific issues that may share the same solution. Microphysical systems (MPSs) are in vitro platforms made up of cells in a microenvironment that closely mimics that found in the body, allowing scientists to recreate the conditions of tissues found within the body for both further elucidation of biological conditions and systems and for applications such as testing drugs in a more precise model than animal testing allows. However, the advancements that MPSs could provide have been limited up to this point by an inability to accurately record what is happening at a cellular level. Now, a team of scientists has developed an electrochemical sensing platform that could solve this issue. The results were published in Biosensors and Bioelectronics.

Scientists have developed a prototype sensor that could help doctors rapidly measure adenosine triphosphate (ATP) and lactate levels in blood samples from patients, aiding in the rapid assessment of the severity of some diseases.
