Magnetic Biomaterials: Medicine You Can Control From Outside the Body Most biomaterials are programmed before they enter the body. Their stiffness is set. Their degradation rate is set. Their drug-release profile is set.
-
Why Biomaterials Break During Commercialization An FDA-approved hydrogel sealant can swell up to 50% in any dimension. That sounds useful. A sealant needs to expand into small gaps and create a barrier.

Biomaterials Testing Barely Changed in 30 Years Biomaterials testing is still mostly done by hand. Walk into a drug discovery lab and the screening runs itself. Robots move liquids across 384 and 1,536-well plates, around the clock, throwing off millions of clean data points.

How Hydrogels Are Turning Deserts Into Forests Deserts have one fundamental problem: They cannot retain water. In arid environments, rainfall evaporates quickly or drains beyond the reach of plant roots. Sandy soils often have extremely poor water retention, making long-term vegetation growth difficult without constant irrigation.

Could Jellyfish Be the Future of Wound Healing? Jellyfish are mostly water. In fact, their bodies are about 95% water, held together by a soft biological matrix called mesoglea. Structurally, this matrix behaves very similarly to what scientists call a hydrogel.

Hydrogels: The Future of Wound Care Every year, millions of people suffer from chronic wounds. Diabetic ulcers. Burns. Pressure injuries. Surgical wounds.

Hydrogels: The Spacesuit of the Future Space isn’t empty. It’s full of energetic particles moving fast enough to damage electronics and living tissue.

Hydrogels are the AI of biomaterials At first glance, it sounds like hype. Hydrogels don’t run code. They don’t train neural networks. They don’t “think” in the way software does.
