The principal aim of the work is to help in the development of a low-cost
biosensor capable of providing a reliable diagnosis to inexpert users. Rather
than being a precise measurement instrument like mass spectrometers, this
biosensor should be able to qualitatively detect and distinguish between the
most relevant families of the bacteria causing mycobacterium tuberculosis in
human fluids. Other approaches pursue outstanding sensitivity relying on
expensive materials and microfabrication processes. Despite other requisites,
low-cost imposes certain criteria regarding materials, systems, fabrication
techniques and user interfaces to be included in the device.Ingeniería Biomédic
