Detection of Glucose with a Self-Made Biosensor 4/5 – Michaelis-Menten Kinetics
In this chapter we discuss the theory of Michaelis-Menten and its importance for biosensors. The last section deals with the Lineweaver-Burk plot.
Detection of Glucose with a Self-Made Biosensor 3/5 – Immobilization of Enzymatic Biosensors
In this section, we elaborate on the workings of biosensors. More specifically, the immobalization thereof.
Detection of Glucose with a Self-Made Biosensor 1/5 – Introduction
This series of articles aims to provide an introduction to electrochemical experiments. This series in particular deals with the detection of glucose with a self-made biosensor based on glucose oxidase, and includes an experiment (PDF) you can carry out yourself.
Detection of Glucose with a Self-Made Biosensor 2/5 – What is a Biosensor?
This chapter is part of the series ‘Detection of glucose with a self-made biosensor based on glucose oxidase’. This section provides a basic introduction to biosensors....

Voltammogram
A voltammogram is a graph that can be drawn after an electrochemical experiment. This graph has a typical, recognizable form in which the electron flow (current: i) is measured in Volt against the potential (E).
Future of electrochemical sensors
Curious how electrochemical sensors will be used in the future? Niels van Velzen, the CTO of PalmSens, explains about biosensor strips and portable readers. The readers perform mea...
Portable potentiostat
In some cases you want to carry out your measurements in the field, in several places and have results available immediately. That is why PalmSens has developed a portable battery-powered potentiostat and a USB-powered potentiostat that you can connect directly to your phone.
Potential
A potential is nothing other than the voltage or electrical voltage of a specific (liquid) substance.
Impedance analyzer
An impedance analyzer is a device that can measure how a particular substance or electrode surface responds to a a potential that is constantly increased and decreased within certain predefined limits (a potential wave).
Galvanostat
If you want to apply a current to a liquid, such as mercury, and want to observe the change of potential, you need a device that can control the former and measure the latter. Such a device is called a galvanostat.
