Chemical Optical Sensors

PreSens offers single-point and imaging devices for oxygen, pH and CO2. Optical sensors allow measurement through the wall of closed vessels, show no electric potential and do not consume the analyte. High spatial resolution of the sensor materials down to 25 µm supports microsensor measurements or imaging e.g. oxygen distributions in packings, biofilms or over engineered or native vasculated tissue. Hypoxic or anoxic conditions of cells, spheroids or tissue may be monitored with high precision over long time periods even at trace level.

Our portfolio ranges from ready-to-use products over OEM partnership to contract development. Frequent customer demands are sensor spots to be integrated in any kind of vessel, microsensors, sensor-equipped microtiter plates and imaging solutions for microscopic or large field-of-view applications.

Optical sensor technology for O2, pH and CO2

What we offer

PreSens develops, produces and sells optical sensors, opto-electronic devices and software solutions for O2, pH and CO2 supporting:
- measurement through the wall of closed vessels
- microsensor measurements with tip sizes below 50 µm
- imaging measurements with hand-helds, microscopes or camera set-ups with large field-of-view

We offer:
- ready-to-use products from stock
- customized prototypes
- OEM partnership
- contract development
- QMS according to ISO 9001 and ISO 13485

Product examples:
- VisiSens for imaging sensor foils up to size DIN A5
- Microx 4 for micro-invasive oxygen measurements
- Fibox 4 for non-invasive oxygen measurement inside vessels

Application examples:
- monitoring of metabolic processes
- (micro)fluidic chips
- bioreactors
- oncology, wounds, regenerative medicine, cosmetics
- packaging

What we are looking for

We are looking for:

a) Application ideas demanding one or more of the following criteria:
- no electric potential at measuring site
- no analyte consumption (O2, pH, CO2)
- measurement through the wall inside closed vessels
- high spatial resolution and precision
- imaging analyte distributions
- multiple measurement sites
- multi analyte measurements
- sensor as disposable
- mobile or hand-held devices

b) New OEM partners
