A team of researchers led by an Indian-American scientist, Ajeet Kaushik from the University of Florida has developed a portable biosensor that can display the progress of Alzheimer's disease in a patient.
This test on the cheap and portable biosensor can reveal accurate information on the progress of the disease and monitor what is occurring to a patient over time, by measuring the level of the protein the betamyloid, the increased level of which leads to degeneration of brain cells and causes the disease. The protein, which is found in lower levels in blood, makes it a useful biomarker to diagnose and monitor the disease progression. It also shows if and when the disease reaches an untreatable level.
"We want to develop a point of care system, where a small drop of blood plasma can reveal their beta-amyloid level immediately so that a doctor can tailor a patient's therapy immediately," said lead author Ajeet Kaushik from the University of Florida in the US.
The researchers also pointed out that the affordable test can be used in developed countries and rural settings. Also with the right data, doctors can respond quickly to changes in a patient's brain by reducing or increasing their dose of drugs.
The research is published in the journal Biosensors and Bioelectronics.
