Looking for Custom Developed Biosensors?

We do custom work

Many of our biosensors are commisioned by government or private entities, and we are able to create custom biosensors that have applications in a wide range of industries from food safety and biodefense to agriculture and mail-screening. If you don’t find the biosensors you are looking for in our Library of Biosensors, contact us. We do custom pathogen testing and will happily work with you. Below are some of the customer biosensors we’ve developed in the past:

Are You Curious About How We Build Our Biosensors?

Technology You Can Count On

All of our biosensors are developed with CANARY® (Cellular Analysis and Notification of Antigen Risks and Yields) technology. This novel detection technology, developed at the MIT-Lincoln Laboratory, utilizes cells that have been modified to express antibodies on their cell surfaces against targets of choice, as well as to express the bioluminescent protein aequorin – which we sourced from jellyfish! Aequorin emits light when exposed to the increases in intracellular calcium levels that occur when the biosensor interacts with the pathogens. Basically, the biosensor cells light up like a glowstick if a threat is detected, which allows our machines to give you fast, accurate results at the speed of light. 

Due to the rapid kinetics and signal amplification of cell-based signaling, detection of pathogens with CANARY® offers sensitivities down to 50 cfu/pfu with a 5 minute time to result. What does this mean? Our technology is faster and more sensitive than the competition, period. Sophisticated algorithms are then used to accurately detect and identify pathogens based on the biosensor light emission, so that you can keep yourself, your employees, and your products safe.

We’re here to help you stay safe
