After over a decade of bio-materials engineering research effort at the University of California, Berkeley (UCB), and Lawrence Berkeley National Laboratory (LBNL), Calyx was spun out with the mission to apply advanced bio-materials to create low-cost and power-efficient sensors for the real-time detection and characterization of airborne chemical compounds.


We leverage the use of genetic and chemical engineering tools to produce non-toxic phage materials for use in highly sensitive sensors for airborne chemicals.  Using drug discovery and tumor cell targeting tools to modify the phages, we make the sensors highly selective.

While our technology platform has received widespread interest from many different industry sectors, we are currently focused on complex aromas and toxic industrial chemicals (TIC), such as formaldehyde, ammonia, and benzene, as initial market entry applications.


We are now actively looking for customers/partners for field pilots and proof of concept testing.

  • Calyx Aroma Analyzer
    The Calyx Aroma Analyzer is a novel ‘electronic nose’ solution for the characterization of complex aromas. It is a complete analyzer for characterizing complex airborne chemical profiles, promising selectivity, extensibility, and versatility....

  • Within the food and beverage industry, rapid examination and identification of sensory anomalies enable on-the-spot decision-making at various stages of product development, production, quality control, and distribution.  Calyx is a portable real-time aroma analyzer that provides flexible solutions for multiple such applications. The Calyx Aroma Analyzer is customizable so that it may be adapted to new problems and individual situations.

    The Calyx Aroma Analyzer incorporates an array of patented phage-based sensors engineered to respond to specific chemical functionalities and structures. It comes complete with on-board sampling and cleaning systems.

    Calyx presents the following highlights:

    • Simple Operation: no time-consuming and costly laboratory sample preparation required; sample processing is automated and convenient
    • Fast Analysis: a typical analysis takes only 5 mins to get results
    • Reliable Results: consistent and reproducible laboratory-grade results in real-time
    • Intuitive Analysis: proprietary algorithm provides metrics to benchmark and compare test samples to other aroma profiles

    Features of Calyx include:

    • Able to characterize aromas from both liquid and dry samples
    • Auto cleaning of instrument after sampling
    • Analyzer software included that shows operation status and timing of sample analysis
    • Power: 100-240 VAC, 50-60 Hz

    With Calyx, our multi-application gas analyzer, the potential is endless. From quality control of food and beverage products from farm to table, development of new fragrance compounds, to safety inspection, we are only beginning to explore the possibilities.

  • M100 Ammonia Sensor
    The M100 is your go-to solution for a fully integrated ammonia sensor. It is wireless, and can operate on battery power for multiple years with minimal calibration maintenance from sub-freezing to 50°C....

  • Calyx’s M100 line of ammonia gas sensors is a fully integrated system with wireless transmission capability, and provides the optimal price to performance metric to operate in any situation. The M100 can be powered via battery or 10-32 VDC power, analyzes ammonia in real time, and transmits the data wirelessly using LPWAN technology.

    Highlights of the M100 ammonia sensor include:

    • Long Operating Life: the M100 can operate for multiple years on battery power with minimal maintenance such as an occasional calibration check
    • Fast Response: the sensor rapidly responds to concentration changes, with a T90 under 60 seconds
    • No Drift: the sensor operates normally in the continuous presence of ammonia
    • Configurable: the operator can choose a wide variety of parameters, such as sampling period, transmission period, and power options.

    Features on the M100 ammonia sensor:

    • Power ON/OFF button on device
    • 4 LED indicators for operation status, updates, and alarms
    • Allows factory and user setting restoration in case parameters are lost accidentally
    • Transmit setup information and battery voltage to wireless receiver
    • On-device sockets for future sensor add-ons
    • Easy to swap lithium ion battery
    • Alternative communication options available
    • Alternative mount options available
    • Lower detection range option available
    • Extended temperature range available

    Operating a M100 is as simple as putting the sensor in the desired location and tuning it on. It gives accurate ammonia readings continuously and automatically.

  • N100 Smart Ammonia Module
    In addition to the comprehensive sensor package offered with the M100, Calyx also offers the N100 Smart Sensor Module with built-in MCU. It is available for developers to integrate into embedded systems....

  • The N100 offers the barebones module version of our ammonia sensor. It has the ammonia sensor, as well as an on-board MCU to provide digital output. The N100 comes in industry standard 4R form factor, and is available for developers to integrate into embedded systems.  

    Highlights of the N100 include:

    • Long Lifetime: the sensor operates normally in the continuous presence of ammonia, and long-term exposure does not decrease sensitivity
    • High Selectivity: the sensor is highly selective to ammonia, and is unaffected by other environmental contaminants such as NOx, SOx, CO2, O2, EtOH, and hydrocarbons
    • Fast Response: the sensor responds to gas changes rapidly, with T90 of under 60 seconds

    Features of the N100:

    • Sensitivity Range: 0 ppm~50 ppm (lower detection and resolution range option available)
    • Nominal weight of 8 grams
    • 3-5V operating voltage
    • UART digital output
    • Humidity Range: 25%~95% (non-condensing)

    Temperature range: -20°C~50°C
