Latest Marshall Porterfield Stories
Purdue University scientists have developed a method for stacking synthetic DNA and carbon nanotubes onto a biosensor electrode, a development that may lead to more accurate measurements for research related to diabetes and other diseases.
A biosensor utilizing black platinum and carbon nanotubes developed at Purdue University will help give scientists a better understanding of how the plant hormone auxin regulates root growth and seedling establishment.
A new biosensor developed at Purdue University can measure whether neurons are performing correctly when communicating with each other, giving researchers a tool to test the effectiveness of new epilepsy or seizure treatments.
Purdue University researchers say they have created a fiber-optic sensor capable of measuring oxygen intake rates in agriculture or medicine. The researchers, led by Associate Professor Marshall Porterfield, said their self-referencing optrode is non-invasive and has applications ranging from plant root development to assessing the effectiveness of chemotherapy drugs. The scientists, including doctoral student Mohammad Rameez, say the device can deliver real-time data without consuming...
