The use of a composite biomagnetic material with microscale magnetic particles and probiotic bacteria, along with an externally applied magnetic field, allows for better localization and retention of probiotic bacteria in the GI tract of mice. This technology enhances the ability of GI-targeted probiotics to accumulate at specific locations and stably colonize without the need for antibiotic treatment, providing external physical control to an important class of microbial theranostics.
Engineered probiotics have the potential to diagnose and treat a variety of gastrointestinal (GI) diseases. However, these exogenous bacterial agents have limited ability to effectively colonize specific regions of the GI tract due to a lack of external control over their localization and persistence. Magnetic fields are well suited to providing such control, since they freely penetrate biological tissues. However, they are difficult to apply with sufficient strength to directly manipulate magnetically labeled cells in deep tissue such as the GI tract. Here, it is demonstrated that a composite biomagnetic material consisting of microscale magnetic particles and probiotic bacteria, when orally administered and combined with an externally applied magnetic field, enables the trapping and retention of probiotic bacteria within the GI tract of mice. This technology improves the ability of these probiotic agents to accumulate at specific locations and stably colonize without antibiotic treatment. By enhancing the ability of GI-targeted probiotics to be at the right place at the right time, cellular localization assisted by magnetic particles (CLAMP) adds external physical control to an important emerging class of microbial theranostics.
