Presently, smart fabrics are manufactured from metallic or optical fibres. They wear away quickly, and are brittle and uncomfortable. Laundry of such textiles also proves to be troublesome. Nano technology has come up with an innovative way of combining the two fibres; one natural and the other nano technology. Cotton yarn with a thickness of 1.5 millimeters is dipped a few times in a solution of a special sticky polymer in ethanol and dried. This enables the yarn to conduct power from a battery to illuminate light emitting diode device. The antibody anti-albumin is added to the carbon nanotube solution. Anti-albumin reacts with albumin, a protein that is found in blood. When the anti-albumin infused yarns were exposed to albumin, the conductivity is increased considerably. This method is more sensitive, simple and durable. By repeating the process a few times, normal cotton becomes a conductive material due to the carbon nano tubes which are conductive in nature. After the process is complete, the cotton yarn still retains its soft and supple features. This yarn is much better comparatively over the current designs available for electrically conducting fabrics. The only change in the yarn is that it turns into black color due to the presence of carbon.
