Designing Ultra-Sensitive Plasmonic Nanobiosensors for Early Personalised Diagnostics

July 3, 2014

(Nanowerk) – A new type of high-sensitivity and low-cost sensors, called plasmonic biosensors, could ultimately become a key asset in personalised medicine by helping to diagnose diseases at an early stage. Personalised medicine is one of the new developments that is deemed to revolutionise health care. A key component is the detection of biomarkers, proteins in blood or saliva, for example, whose presence or abnormal concentration is caused by a disease. Biomarkers can indicate the presence of diseases long before the appearance of symptoms. However, currently the detection of these molecules still requires specialised laboratories and is costly.
