The need for point of care diagnostic tests has increased enormously in the last few years. Nanomaterials in general and particularly nanoparticles thanks to their optical and electrochemical properties are bringing significant advantages in the design and application of novel biosensors and in this context of diagnostics tests. Biosensors represent an interesting alternative for the development of efficient, fast, low-cost and user-friendly diagnostic devices. Between different biosensing alternatives the nanotechnology and nanomaterial oriented biosensors represent a very attractive tool for clinical applications. Several applications related to DNA, protein and even cell detections based on the use of nonoparticles will be described. The developed devices are based on the use of various platforms which allows their easy applications in diagnostic. The developed devices take advantages of both enhanced electrochemical (i.e. electrocatalytic) or optical (i.e. light absorbance) properties of nanoparticles while being used as labels in immunoreactions or DNA hybridization reactions.
