Gold nanoparticles have generated particular interest in the field of biosensors due to their physico-chemical characteristics and ease of synthesis and functionalization. The unique physical and chemical properties of gold nanoparticles have stimulated increasing interest in the design of a new generation of biosensors. Their high surface-to-volume ratio and biocompatibility, make them a large number of interaction sites, thus improving the amount and activity of the recognition.
Regardless of the role that gold nanoparticles play in the detection process, they offer several advantages over conventional dosage formats such as a single preparation, good stability, easy use, real-time measurement and low cost. With different types of signal transducers, the physical or chemical changes that occur during the binding of the analyte to the bioreceptors of biosensors can be transformed into optical, electrical, or qualitative output signals etc.
At TORSKAL, our team is experienced in the field of gold nanoparticles-based biosensors and can guide you in the design of the biosensor from the bioreceptor selection to the detection of your target. We can also help you to improve the analytical performance of your target detection in terms of sensitivity.
