Tuberculosis (TB) is believed to affect nearly one third of the world population with approximately 9 million new cases detected every year. Current methods of diagnosis includes sputum smear microscopy, chest X-Ray and biopsy which are time consuming and expensive with a low level of accuracy. The project aims at the fabrication of a disposable sensor strip and an indigenously developed meter for the point of care testing of tuberculosis. This is achieved by the immobilization of the highly selective peptide on a screen printed carbon electrode. A software will be developed and integrated with the electronic meter for converting the measured impedance into the target protein concentration. By developing a disposable strip and a meter for the early detection of tuberculosis, affordable and point-of-care diagnosis can be realized.
