Dr. Netz Arroyo pursues the development of wearable and implantable biosensors allowing the real-time monitoring of normal physiology and disease states in vivo. Dr. Arroyo’s research lab uses DNA as a molecular recognition tool, and integrates the DNA into electronic devices for biomedical sensing applications. Our most current research efforts are focused on translating DNA aptamer-based sensors to in-human clinical use.

Dr. Arroyo received his undergraduate degree in Chemical Sciences from Tec de Monterrey (Mexico). He earned his Ph.D. in Analytical Chemistry from The University of Texas at Austin, under the mentorship of Allen J. Bard. He completed postdoctoral work with Kevin Plaxco in Bioengineering at the University of California Santa Barbara. Dr. Arroyo joined the Johns Hopkins Medicine faculty in 2019.

He is a member of the American Chemical Society, the American Society for Pharmacology and Experimental Therapeutics, and the Electrochemical Society. His work was recognized by the journal ACS Sensors in 2020, naming Dr. Arroyo a Rising Star in Sensing.

Origin of his name: The name Netzahualcóyotl comes from Náhuatl and means “coyote who fasts.” It is the name of one of the most iconic characters of pre-Columbian Mexican history: ruler (tlatoani) of the city-state of Texcoco, philosopher, warrior, architect and poet. The name was given to Netz right at the moment of his birth, mainly promoted by his father (who was Mexican) yet immediately adopted by his mother too (who is Spanish). Netz believes that his name has played a fundamental role in shaping his personality and is proud of its historical roots. An anecdote he often tells about his early life recalls the time when he was in kindergarten and had to learn how to write his own name. While all the other kids with simple names were able to do it rather quickly, it took little Netz a greater effort to accomplish the task since he had all the difficult letters from the alphabet in his name (without considering the count!). more
