For seven years, Dr. Eleanor Stride has been developing a new way to deliver drugs: injecting tiny bubbles. By containing medicine within a "micro-bubble" and targeting where the bubbles go (some are magnetic, and can thus be literally dragged around), the medicine's release can be highly targeted. This approach has the potential to dramatically reduce the destruction caused by chemotherapy, by targeting the toxic effects of the drug to just the tumor, rather than the body as a whole.
In this short video, Stride explains her research, and we see some beautiful slow-motion footage of bubbles. More like this, please:
For more technical detail, here's a 10-minute interview with Dr. Stride:
