Our Technology

En Carta leverages a wide array of tools from the exciting field of synthetic biology. ​


At the edge of innovation, we leverage laboratory science

to make accessible and reliable healthcare tools.



Our sensors are built from RNA or DNA. Groundbreaking proprietary technology derived from toehold switches can detect any pathogen's RNA or DNA, down to single-nucleotide precision.

With the cost of "printing" DNA rapidly coming down,

our patented technology has a competitive advantage that grows fast.


By freeze-drying our sensors in any porous materials, we can store and ship accessible diagnostics everywhere, eliminating the need for cold chain.


Our systems are optimized for a single step reaction with visual readout that can be run and interpreted by anyone.


Our testing cassette ensures optimal reaction conditions yet does not require alkaline batteries.


En Carta technology powers first and only true molecular
point-of-care diagnostic devices offering PCR- grade accuracy
without external power source
