Due to their exceptional mechanical and chemical properties and their natural abundance, cellulose nanocrystals (CNCs) are promising building blocks of sustainable polymer composites. However, the rapid gelation of CNC dispersions has generally limited CNC-based composites to low CNC fractions, in which polymer remains the dominant phase.

Velcro-like food sensor detects spoilage and contamination

MIT engineers, including Professor John Hart have designed a food sensor from an array of silk microneedles that pierces through plastic packaging to sample food for signs of spoilage and bacterial contamination.

Engineers 3-D print flexible mesh for ankle and knee braces

MIT engineers including Professor John Hart and Professor Neville Hogan have designed 3-D-printed mesh materials whose flexibility and toughness emulates and supports softer tissues such as muscles and tendons.
