Levi Diagnostics is a research and development startup specializing in the application of nanotechnology innovations.


The company was incorporated at the end of 2019 with a mission of delivering revolutionary nanosensor technologies to government agencies, private sector clients, and consumers. We focus our efforts on three major areas: rapid viral diagnostics, narcotics detection, and diagnostics of women's diseases.

AT the LAb

As a subsidiary of Emitech Inc. (, we are able to leverage a combined 20 years of experience in the field of nanotechnologies for various sensing applications.  Emitech has been successful in working with both government grants and private sector investors.

We have multiple US patents for the design and implementation of high-sensitive detection technologies.


  • November 2019:  Levi Diagnostics, Inc. was incorporated.

  • September 2020: Emitech, Inc (parent company of Levi Diagnostics) received an SBIR grant from NIDA, National Institute of Drug Abuse (one of the National Institutes of Health, NIH ) for the development of wearable nanosensors for rapid opioids detection.

  • October 2020: Levi Diagnostics technology for drug detection received an excellent evaluation from the international marketing company dealing with the transition of innovative technologies to the global market. The average score of 1.53 based on 15 parameters was issued on the scale from

       1 (excellent) to 9 (poor).

  • November 2020: Strategic alliance was established between Levi Diagnostics and Loft ( Company specialized in the development and sale of various digital gadgets including wearable medical devices.

  • February 2021: LD-COVID detection technology was selected by TechConnect’s internal review panel of innovation experts for participation in the COVID-19 Innovation Showcase on February 17, 2021. (

  • May 2021: Levi Diagnostics became a member of the Medical Technology Enterprise Consortium, MTEC (
