Proof-of-concept

The technique has been proven for:

TARGETs: nicotine, serotonin, histamine, caffeïne, malachite green, biogenic amines, …

ANALYTEs: buffer solutions, water, saliva, urine, blood plasma, wholeblood, …

Dose-response curve of

nicotine in PBS

=> LOD ~ 30 nM

HTM-determination

of serotonin in non-diluted blood plasma

State-of-the-art

- Use of bulk-MIPs

- Stamping technique / spraycaoting

- Flow-cell and drop-cell

- Home-made setup

Valorisation

• What are the most interesting TARGETs? (market potential, emerging technologies, FTO, etc.)

• Detection limits and dynamic range?

• Complexity of the analytes (preparation necessary?)

• Single testing or multi-parameter testing?
