Flow biosensing and sampling in indirect electrochemical detection

Determination of sulphite in wine by flow injection analysis with indirect electrochemical detection

A flow-injection method has been developed for the determination of total sulphite in wine samples. After hydrolysis of bound sulphite, sulphur dioxide is separated from the matrix by means of an in-line gas diffusion module. For detection indirect amperometry is used, with iodine as oxidizing reagent. The iodine can be generated in-line by merging and mixing iodate and iodide solutions, or alt...

Electrochemical Biosensing with Carbon Nanotubes

Biosensing at an Individually Addressable Electrochemical Array

Do Carbon Nanotubes contribute to Electrochemical Biosensing?

Carbon nanotubes have been attracting a lot of interest as electron transfer mediators to enhance electrochemical biosensing. The main reason behind this is usually recognized in terms of augmented electrochemical active surface area. The aim of this paper is to review other phenomena that occur at the electrochemical interface. Three distinct features of these phenomena mainly appear in electr...

Fullerenes in Electrochemical Catalytic and Affinity Biosensing: A Review

Nanotechnology is becoming increasingly important in the field of (bio)sensors. The performance and sensitivity of electrochemical biosensors can be greatly improved by the integration of nanomaterials into their construction. In this sense, carbon nanomaterials have been widely used for preparation of biosensors due to their ability to enhance electron-transfer kinetics, high surface-to-volume...
