Nitric Oxide Absorbing Hydrogel Releases Drugs to Fight Rheumatoid Arthritis, Other Diseases

At the Institute for Basic Science in Daejeon, South Korea, scientists have developed a hydrogel that responds to the presence of nitric oxide (NO) and releases drugs when so activated. This kind of drug delivery system may be particularly effective for treating rheumatoid arthritis, as immune cells within inflamed joints release toxic NO in large quantities. … Continue reading

Robots Made of Hydrogels May Help Surgeons Operate on Fragile Tissues

The future of surgery may involve robotic devices that are soft and gentle to prevent unwanted damage, yet strong enough to be able to manipulate tissues. At MIT engineers are leading the way toward that future having developed robots made out of hydrogel and powered by water, that can, among other things, grab and release … Continue reading

Tough Injectable Hydrogel to Help Hearts Recover After Heart Attack

At the national meeting of the American Chemical Society, researchers from University of Pennsylvania are showing off a new hydrogel that may be used to help ailing hearts recover post myocardial infarction. There are already a few hydrogels developed, some going through clinical trials, for helping restore cardiac function. UPenn’s material was developed to result in … Continue reading

New Technique for 3D Printing of Soft Body Tissues from Hydrogels

3D printers are already actively used to print hard replacement parts for people with skull damage, deformed trachea, and a few other conditions. Work is underway to be able to print soft, functional tissues that promote cellular growth and may one day be used to replace entire organs. At Carnegie Mellon’s Regenerative Biomaterials & Therapeutics Group … Continue reading

Injectable Hydrogel Material Serves as Scaffold to Heal Wounds

At UCLA researchers have designed an injectable hydrogel scaffold that promotes wound healing by serving as a 3D platform within which new tissue can grow. The interconnected material has tiny pores into which new cells can migrate and grow within, while it maintains the structural integrity and helps nutrients reach the newly growing cells. The … Continue reading

Smart Hydrogel Draws Special Repair Cells to Fix Broken Cartilage

The confocal image shows chondrogenic progenitor cells migrating into the cartilage injury site in response to the stromal cell-derived factor 1(SDF1) contained in the hydrogel. Very sadly for many of us, cartilage is a tissue not known to naturally repair itself. That’s an important reason why so many professional sporting careers end abruptly and why … Continue reading

New Injectable Hydrogel Helps Cells and Vessels Grow (VIDEO)

Hydrogels have been shown before to be a medium that promotes new cell growth, potentially serving as a material that can help repair damaged organs. One major obstacle that has kept hydrogels largely absent from this kind of clinical applications has been the inability of high quality blood vessels to form within the material. Typically, … Continue reading

Hydrogel Scaffold With Self-Forming Fibers Highly Effective for Burn Wounds

Researchers at the Institute of Bioengineering and Nanotechnology (IBN) in Singapore developed a “nanogel” that’s excellent at promoting the healing of second and third degree burns in animal studies. The material is made out of peptide hydrogels that works like a scaffold within which cells can grow. When water is added to this scaffold, the peptides … Continue reading

3D Printed Hydrogel Seeded with Nanoparticles Filters Toxins Similar to Dialysis

PDA nanoparticles (green) are installed in PEGDA hydrogel matrix (grey) with liver-mimetic 3D structure fabricated by 3D printing. The nanoparticles attract, capture and sense toxins (red), while the 3D matrix with modified liver lobule structure allows toxins to be trapped efficiently. Nature Communications Engineered nanoparticles have the capacity to grab onto toxins, but evacuating them … Continue reading

Rice Thermogelling Hydrogel Turns Hard When Injected Into Body to Support Stem Cells (VIDEO)

Bones break and softer tissues get damaged in a variety of ways, but new technologies, especially patient-derived stem cell, can help restore them to a healthy state. Stem cells, while extremely competent at differentiating into target tissues, have to be delivered and kept at the therapy site long enough to do their thing. Researchers at Rice University developed … Continue reading
