To Boldly Go
Here, researchers present a magnetic microrobot system designed for delivering cancer-targeting drugs in challenging environments such as our very acidic (pH2) stomach. Demonstrated here in pig stomach, a pH-responsive coating protects the drug cargo during transit and then degrades upon pH change, to release the drug-carrying nanoparticles

What is BPoD?
BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
