Company profile

researched Aug 2026

Infusense is a Nashville-based biosensor company developing an electrochemical technology platform for drug quantification. The platform is presented as achieving analyte detection limits at sub-therapeutic levels, with sample analysis completed in a few minutes.

The company's stated approach uses electrochemistry (voltammetric measurement) to measure target analytes, with the aim of delivering full-scale laboratory measurement capability in a handheld form factor. Publications listed by the company cover electrochemical sensors for tricyclic antidepressants (amitriptyline and nortriptyline in blood) with low nanomolar detection limits, polymeric and plasticized PVC membrane-modified voltammetric sensors for lipophilic and highly hydrophobic compounds, and voltammetric measurement of propofol (2,6-diisopropylphenol) in serum-like electrolyte solutions oriented toward feedback-controlled anesthesia. A publicly announced program targets a rapid fentanyl toxicity test.

Traction

Infusense reported a $1 million NSF SBIR grant to advance a rapid fentanyl toxicity test and an SBIR/STTR matching funds award from Launch Tennessee. The company was scheduled to present at LSTCON 2024, the Life Science Tennessee conference, and has been featured in Teknovation.Biz coverage. Its scientific work appears in peer-reviewed literature indexed by the National Library of Medicine, ScienceDirect and ACS Publications.

Full profile — market position, technology, go-to-market, geography, history

Market position

Infusense positions its platform as bringing laboratory-scale drug quantification into a portable, point-of-need format, with applications in drug toxicity testing and anesthesia monitoring.

Technology

The core technology is an electrochemical (voltammetric) sensing modality, including polymeric membrane-modified and plasticized PVC membrane-modified electrodes, used to quantify lipophilic and highly hydrophobic compounds. Reported characteristics include nanomolar and sub-therapeutic detection limits and sample analysis times of a few minutes, with the electrochemical approach enabling a handheld, palm-sized device rather than laboratory instrumentation. Application areas indicated by company-listed publications and programs include tricyclic antidepressants (amitriptyline, nortriptyline) in blood, propofol measurement for feedback-controlled anesthesia, and fentanyl toxicity testing.

Go-to-market

Clinical and point-of-care settings requiring rapid drug quantification, including toxicity testing (fentanyl) and anesthesia monitoring (propofol).

Geography

Headquartered in Nashville, Tennessee, United States, with ties to Tennessee-based organizations including Life Science Tennessee and Launch Tennessee.

History

Edward Chaum, M.D., Ph.D., is identified as founder and chairman of the board. The company's website carries a 2023 copyright notice, and reported milestones include a 2023 Innovation Award to advisor Dr. Erno Lindner, an NSF SBIR grant of $1 million for a rapid fentanyl toxicity test, an SBIR/STTR matching funds award from Launch Tennessee, and a scheduled presentation at LSTCON 2024.
