Researchers Create Implantable Sensor for Continuous Inflammation Tracking in Vivo

Northwestern University has made a groundbreaking advancement in biomedical engineering with the development of an implantable device that monitors fluctuating protein levels in real time. This technology could revolutionise patient care, particularly for those managing chronic diseases.

The device, as thin as three human hairs, was successfully implanted into diabetic rats in initial experiments. In these trials, the device demonstrated high accuracy and sensitivity in measuring inflammatory protein biomarkers, a significant step towards understanding inflammation better.

The technology utilises strands of DNA that attach to proteins, shake them off, and then capture new ones. This novel approach allows for dynamic monitoring of a wide range of proteins, not just static measurements, which could expand biomedical understanding and clinical decision-making across multiple diseases.

Hossein Zargartalebi, a postdoctoral fellow, developed a method to overcome the challenge of creating sensors for larger and more complex proteins by using an alternating electric field to oscillate the DNA strands. This innovation has enabled the device to track critical proteins, including cytokines associated with inflammation and biomarkers relevant to heart failure.

Shana O. Kelley, the study's lead researcher, compared the device's functionality to that of a continuous glucose monitor. The sensors accurately reflected cytokine concentration changes in response to immune system stimulation and monitored changes in inflammatory protein levels during fasting and insulin administration.

This breakthrough represents a significant leap forward in biomedical engineering and patient monitoring technologies. The study will be published in the prestigious journal Science.

The key potential applications of this device include diabetes management, chronic disease therapy, biologic drug delivery revolution, and real-time biomarker measurement. With continuous monitoring, doctors could adjust treatments proactively before symptoms worsen. By integrating bioelectronics with engineered living cells housed in the implant, it enables continuous, on-demand production and delivery of biologic drugs (e.g., insulin or anti-inflammatory agents) within the body. This reduces the need for frequent injections and supports sustained treatment adherence, benefiting conditions like autoimmune disorders.

The device's development is supported by Northwestern's Ryan Family Research Acceleration Fund, emphasising its translational potential towards clinical use and commercialisation. This innovation promises to improve treatment consistency, reduce patient burden, and enable personalised medicine approaches, marking a significant advance in biosciences and therapeutic technologies. The technology could revolutionise patient care much like continuous glucose monitoring has for diabetes.
