Netz Arroyo's Biography

Netz Arroyo, Assistant Professor of Pharmacology and Molecular Sciences, Johns Hopkins School of Medicine

I am an experienced analytical chemist with a deep understanding of the fundamentals of electrochemistry. My contributions to the field of electroanalytical chemistry span more than 8 years and include studies of electrocatalytic surfaces by scanning electrochemical microscopy (SECM), homogeneous reactions coupled to electron transfer events, and the development of an alkaline redox flow battery. For my postdoctoral training, I intentionally broadened my skills by moving into the fields of in vivo sensing and pharmacology. Specifically, I developed an electrochemical biosensing platform supporting the continuous measurement of specific small-molecule targets in the body. Using this platform, my research program aims to: 1) further our understanding of drug and metabolite transport in the body, 2) develop metabolism-responsive approaches to drug delivery and 3) produce diagnostic platforms for the point-of-care monitoring of disease progression.

Personalized drug therapy seeks to tailor treatment to the individual, taking into consideration each person’s unique genotype and metabolism to determine a dose that maximizes drug efficacy and avoids toxicity. Realizing this goal has been extremely challenging, however, for two main reasons. First, it is difficult to determine the optimal drug dose for each patient due to our limited understanding of pharmacogenetics and physiology. Second, even the most sophisticated drug delivery approaches fail to account for hour-to-hour fluctuations in an individual’s metabolism driven by changes in health status, diet or drug interactions. Thus, there remains a pressing need for technologies supporting the real-time, in-vivo monitoring of drugs that would enable patient-specific, metabolism-responsive dosing. In response to this need, our laboratory pursues the development of reagentless sensing approaches that support continuous measurement in the body. During this talk, I will describe an electrochemical approach that relies on DNA aptamers to perform real-time monitoring of small molecule targets, and the use of this approach to study pharmacokinetic changes in rats that originate from biological and metabolic variability.
