Microfluidic encapsulation for subcutaneous delivery of viscous drugs
Antibodies and other biopharmaceuticals have emerged as a powerful new class of drugs for treating diseases that range from rheumatoid arthritis to breast cancer to macular degeneration. However, these large, protein-based molecules cannot be taken orally (the stomach would digest them) and are frequently given at high concentrations. Most are administered intravenously, but that approach... -
T cell traps
T cells, a subtype of white blood cells, play key roles in cell-mediated immunity, be it to fight infections and cancer or, when corrupted, to react against the body’s own cells in more than 80 autoimmune diseases, including type I diabetes, multiple sclerosis, rheumatoid arthritis and others. However, isolating disease-related T cells from the body... -
Ultra-Strong Flexible Biomaterials
Hydrogels are already being developed for use as scaffolds for tissue engineering, vehicles for drug delivery, actuators for optics and fluidics, and models for biological studies of tissue-supporting material called the extracellular matrix. But these water-rich polymer gels are weak; they rupture if stretched just a little, and they break easily compared with resilient biological... -
Tethered Liquid Perfluorocarbon (TLP), a non-stick coating for medical devices
Every device implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient it is meant to help: blood clotting and bacterial infection. To confront this challenge, Wyss Institute researchers created a super-repellent, Thin Layer Perfluorocarbon (TLP) coating specifically designed to prevent clot formation... -
Dynamic Daylight Control System
In the U.S. alone, commercial and residential buildings account for more than 40 percent of the total energy consumption – mostly for lighting. What’s more, the deep building layouts that are typical in the U.S. have led to a complete reliance on artificial lighting systems that are less desirable than natural daylight. Many of the... -
Shrilk Biodegradable Plastic
Wyss Institute researchers have developed a fully degradable bioplastic by isolating a material called chitosan found in shrimp shells and forming a laminate with silk fibroin protein that mimics the microarchitecture of natural insect cuticle. The new material, called “Shrilk”, can be used to manufacture objects without the environmental threat posed by conventional synthetic plastics,...

Video/AnimationFouling Marine FoulingMarine fouling occurs when organisms attach themselves to underwater objects like boats, rope, pipes and building structures. Mussels are one of the biggest culprits. Once attached, they are difficult to remove, leading to operational downtime, increased energy use and damage. Paints and coatings are currently used to prevent marine fouling, but are frequently toxin-based and not... -
Video/AnimationRoboBee: From Aerial to AquaticThe RoboBee is a miniature robot that has long been able to fly. But what if the RoboBee lands in water? Using a modified flapping technique, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering at Harvard University have demonstrated that the RoboBee... -
Video/AnimationSLIPS‘SLIPS’ technology, inspired by the slippery pitcher plant that repels almost every type of liquid and solid, is a unique approach to coating industrial and medical surfaces that is based on nano/microstructured porous material infused with a lubricating fluid. By locking in water and other fluids, SLIPS technology creates slick, exceptionally repellent and robust self-cleaning... -

Video/AnimationTough GelA team at the Wyss Institute is honing a tough, rubbery hydrogel initially developed at Harvards School of Engineering and Applied Sciences. The gel is 90 percent water, yet it stretches without breaking to more than 20 times its original length and recoils like rubber, the researchers first reported in Nature in 2012. In fact,...
