Droplet Instruments
Advanced characterization of surfaces
We offer state-of-the-art technologies, custom services and scientific consulting for your surface characterization needs. We are searching for customers, partners and investors.
Interested? Please contact us at droplet-instruments@aalto.fi.
Droplet Instruments can facilitate:
- early detection of surface degradation and contamination
- optimization of coating adhesion
- understanding the effect of roughness on wetting properties
- studying ink adhesion to improve printing quality
- and more
We are a multidisciplinary team with unique expertise in soft matter (Prof. Robin Ras) and robotic instruments (Prof. Quan Zhou) working on the development of the most precise and accurate measurement techniques for surface characterization.
With a decade of academic experience in developing high-end hydrophobic surfaces for real-life applications we know the difficulties in reliable and efficient surface wetting characterization. [1-3] As such, we have developed innovative instruments for faster and more accurate measurement of liquid-solid interactions.
