Adapting Electrochemical Sensing to Population-Scale Monitoring of SARS-CoV-2 Infection Spread

Dr. Netzahualcóyotl (Netz) Arroyo Currás
Assistant professor in the Department of Pharmacology and Molecular Sciences

Date: September 16, 2020

Time: 1000-1100 AM ET

SARS-CoV-2 has infected over 22 million people globally, leading to ~800 thousand deaths in just ten months. However, significant uncertainty continues regarding the prevalence of asymptomatic and mild cases of COVID-19, the disease caused by SARS-CoV-2, as well as the magnitude, effectiveness, and duration of antibody responses. Gaining a better understanding of population immunity is critical to improving predictive models of infection spread and safely reopening economies worldwide. However, to fill knowledge gaps in these areas requires population-scale testing using low-cost, non-invasive, and highly specific and sensitive assays that can be deployed broadly and serially to characterize antibody responses to SARS-CoV-2. Benchmark detection approaches are based on sandwich immunoassays relying on optical readouts of fluorescence emission or color change to report antibody levels. These technologies can be costly, often require centralized facilities with trained personnel, and are, therefore, not amenable to at-home testing. More affordable technologies, such as lateral flow assays, can be inaccurate or prone to user misinterpretation. Motivated to circumvent such barriers, the Arroyo lab has undertaken a journey to develop an at-home electrochemical assay. This presentation reports the results of our initial, 3-month effort to produce a portable immunoassay.

Netz Arroyo’s background

Netzahualcóyotl Arroyo Currás (Netz Arroyo) is an assistant professor in the Department of Pharmacology and Molecular Sciences at Johns Hopkins University School of Medicine. He obtained his PhD in Analytical Chemistry from the University of Texas at Austin, where he worked with Allen J. Bard on electrochemical energy storage and studies of electrocatalysis employing scanning electrochemical microscopy. He graduated in 2015 and moved to California to complete his postdoctoral training with Kevin W. Plaxco at the University of California Santa Barbara, where he developed electrochemical biosensing platforms supporting real-time measurements of specific molecular targets in the body. His current research focuses on the development of electrochemical biosensors for pharmacological applications. He loves swimming, running, and axing down tree stumps at his home in Maryland.

We thank our webinar sponsor, whose support makes this complimentary program possible.
