A pill that samples gut bacteria from specific areas in the intestines

Official title: Ingestible Pill for spatially targeted sampling of gut microbiome

Funded at Tufts University Medford · NIH-11138897 · Data updated 2026-11-12

This study is testing a tiny pill that you can swallow, which collects samples from your gut to help doctors learn more about your gut health without needing any invasive procedures.

Who could benefit from this research

Could help

Ideal candidates for this research are adults over 21 years old who may require gastrointestinal sampling for health assessments.

Less likely to help

Patients with conditions that prevent them from ingesting pills or those who do not require gastrointestinal sampling may not benefit from this research.

What this research studies

This research focuses on creating a small ingestible device called a micro-pill that can autonomously collect samples from specific locations in the gastrointestinal tract. Unlike traditional methods that require invasive procedures, this micro-pill uses sensors to detect pH and oxygen levels to determine when and where to sample intestinal content. It is designed to operate on a battery and can be activated wirelessly, making it suitable for patients with varying gastrointestinal conditions. The goal is to improve the understanding of gut microbiome composition without the need for invasive surgeries.

Why it matters

Potential benefit: If successful, this research could provide a non-invasive method for patients to better understand their gut health and microbiome.

How similar studies have gone: While the concept of ingestible devices is not entirely novel, the specific approach of this micro-pill for targeted sampling is innovative and has not been widely tested.
