- Electroactive enzymatic compounds for use as substrates of alkaline phosphatase-based assays
Take your research one step further – with our carbon nanomaterials for electrode modification and other applications.
Carbon nanotubes, graphene, and graphene oxide: These allotropes of carbon are among the most studied and most widely applied compounds because of their electrical and thermal properties, their large specific surface area, as well as their strength and elasticity.
For catalysis, sorption, or photovoltaics applications, for example, carbon nanofibers and mesoporous carbon offer great potential. We supply these materials in different sizes and structures and in solid form or in solutions (organic or aqueous).
Metal nanowires and nanoparticles
The properties of materials in the nanosize range differ from those of the corresponding bulk materials.
Our range of metal nanowires and nanoparticles, produced via the electrochemical deposition on alumina templates, can be used in research by acting as biological tags, as catalysts in nano-optics, or in molecular electronics.
You can obtain nanowires and nanoparticles of the following metal in ethanol solution: gold, platinum, palladium, nickel, silver, platinum-gold-nickel
Quantum dots: quantum mechanics at play
Quantum dots offer excellent opportunities in fields such as (bio)sensing and photovoltaics and can be used as photo catalysts. Quantum dots are small enough to produce a quantum confinement effect with different optoelectronic properties. Exhibiting broad excitation spectra with narrow and symmetric emission, these nanoparticles are highly innovative materials.
Our quantum dots are available in a chloroform suspension or functionalized with carboxyl groups, making them soluble in water and thus expanding the scope of application even further.
Electroactive enzymatic compounds: Lowering the limits of detection
Using alkaline phosphatase (AP) as an enzymatic label can help you achieve lower limits of detection. With the electroactive enzymatic products obtained from p-aminophenyl phosphate, hydroquinone diphosphate, and phosphorylated paracetamol, you can achieve simple electrochemical detection while increasing sensitivity and getting wider linear ranges than would be obtained with other standard AP substrates.
Oxidation potentials of the enzymatic products are lower than those of other AP products, thus reducing the number of potential interferents able to be oxidized at the electrode surface.
