PANDa: a fully automated field analyser
To detect micropollutants in water via microfluidics. PANDa is able to detect trace metals such as arsenic from 1 ppb. Other metals such as lead, chromium or mercury will be launched shortly. The analyser works like a printer with a specific cartridge per analytic parameter.
It can analyse 4 different samples with 3 replicates per sample in the same cycle.
The heart of PANDa analyser benefits from the best of our “Lab-on-a-chip” technology. The microfluidic chip embed 3 electrodes acting as an electrochemical cell. Electrovalves, UV- lamp, heating tank and manifolds are fully integrated on our lab and are controlled and automatized by a dedicated electronics.
Our collaborative projects in 2021
FLAshMoB- Functional Amyloid Chimera for Marine Biosensing
The aim is to develop small, portable, easy to use, and robust biosensor platforms to monitor marine contaminants with high sensitivity and specificity, offering the ability to work on site and in a wide range of matrices.
SURIMI-SUrface plasmon Resonance for In situ detection of Metallic Ions
The aim of the SURIMI project is to develop multi-detection metallic element sensors capable of performing robust and sensitive analyses in settings ranging from a laboratory environment to the harshest conditions (e.g. deep ocean and/or polar seas).

NEMO- NEw biomimetic Lab-on-Chip device for marine water MOnitoring
The project relies on a recognition phase based on electrochemical molecularly imprinted polymers (MIPs).
MIP based sensors will be incorporated into glass-based LoC devices. Sampling handling will be tailored in this programme to deliver deployable sensing platforms whereby in-situ sensor measurements in the marine environment will directly indicate specific organic pollutant concentrations.
Glass microfluidic technologies are not considered as simple consumables of laboratory which can be trashed just after use. The main reason is easy to understand. Due to the required facilities and equipment’s, the cost of fabrication of glass chips is one of the highest on the market compare to others classical plastics technologies. In LabInGlass we are aware that our product are valuable items.
Lots of end users often asked us some tricks to reuse and restore their chips. Based on her long experience in Klearia’s group, we will give you some small secrets to take care about your product…
How to clean and store your microfluidic chip in glass?
“Depending on your experiment requirement obviously, but we always flush all the channels with Deionized water in order to remove maximum of dusts, polymers residues, precipitates. Tap water is not recommended because we don’t control its “hardness” and the possibility of limestone residual coating.
Then flush it with Isopropanol and dry it with filtered air gun.
For a long term storage, I advise to fill the channels with Nitric acid at 0.1M but don’t forget to hermetically sealed the channel!!”

Tips & Tricks
The Klearia foundry is hosted on SOPHIA ANTIPOLIS technopole in CNRS/ CHREA laboratory.
The chips are manufactured on an ISO 6 cleanroom with large range of high level equipment’s dedicated for thin layers processing, lithography and etching (e-beam evaporator, Joule-effect evaporator, Sputtering, Mask aligner,…),
