Lead detection from Blood Sample using Biosensor

Abhishek Bhowmik, Rashmi Rameshwari


Devices based upon bio sensors that work with biomaterials such as blood, urine, or saliva are being developed to improve ability to detect chemical exposures in environment and disease. Different types of pollutants like heavy metals are present in the environment. Among these toxic metals, lead composition is maximum in atmosphere. Despite of the considerable works to identify and eliminate lead sources, this metal still remains a significant health concern, particularly in young children and to those who travels in heavy traffic for three to four hours. Even Infants and frequent travelers are also exposed to lead emitted by different automobiles. As lead gets accumulated in lungs and cause severe congestion, breathing problem and sometimes it leads to cancer. So, in order to keep a precise check of the level of lead in the human blood a detection device is necessary to be deduced. A basic device which works on the idea of signal transmission and conversion to detectable signals. This device would be able to detect the trace amounts of lead in blood which would be helpful in the field of medical science.
