Single-Cell Encapsulation for Improved Cell Therapies
Mesenchymal stromal cells (MSCs) are valued for their ability to secrete compounds that modulate the body’s immune system, making them an attractive solution for existing problems with cell therapies including host-vs-graft disease and organ transplant rejections. However, MSCs are rapidly cleared from the body and can come under fire from the immune system. Efforts to... -
RAPID: Testing for Food Contaminants
Contamination of food by microorganisms such as certain bacteria, viruses and fungi is a constant concern, with even miniscule amounts of certain species posing a risk for foods to become unsafe and spoiled during storage. Current safety and quality tests are often not sensitive enough to detect rare species, and because they first require the... -
milliDelta: Millimeter-Scale Delta Robot
Delta robots are deployed in many industrial processes, including pick-and-place assemblies, machining, welding, and food packaging. Three individually controlled lightweight arms enable fast and accurate motion of an output platform in three directions. Roboticists have reduced the size of Delta robots for tasks in limited workspaces, but so far, using conventional manufacturing techniques and components,... -
HAMR: Versatile Crawling Microrobot
Small or difficult-to-access spaces such as areas covered with rubble, or narrow pipes and engines can pose obstacles to search-and-rescue missions, repair works, or environmental and industrial monitoring. One solution for these problems could be small-sized robots that are able to navigate such spaces, transport payload, sense, and communicate. Wyss Institute researchers have developed a... -
FcMBL: Broad-Spectrum Pathogen Capture for Infectious Diseases
Microbial infection is the cause of life-threatening cases of sepsis, meningitis and multiple other diseases that are major causes of death world-wide. Equally prevalent are pathogenic contaminants in our environment, food, and manufacturing processes. In each case, the presence of dangerous microbes must be confirmed, and when they are found, they need to be removed,... -
Human Organs-on-Chips
Clinical studies take years to complete and testing a single compound can cost more than $2 billion. Meanwhile, innumerable animal lives are lost, and the process often fails to predict human responses because traditional animal models often do not accurately mimic human pathophysiology. For these reasons, there is a broad need for alternative ways to...

Video/AnimationInterrogator: Human Organ-on-ChipsThis video describes the “Interrogator” instrument that can be programmed to culture up to 10 different Organ Chips and sequentially transfer fluids between their vascular channels to mimic normal human blood flow between the different organs of our body. Its integrated microscope enables the continuous monitoring of the tissues’ integrities in the individual organ chips... -
Video/AnimationNanofiber-Reinforced Micro-ActuatorsThis video explains how two fabrication techniques, soft lithography and rotary jet spinning of nanofibers, are combined to create a new type of micro-actuator for the manipulation of small fragile objects in challenging environments.

Video/AnimationMORPH: A new soft material microfabrication processWhat has the ability to move and show its colors, is made only of silicone rubber and manufactured at the millimeter scale? A soft robotic peacock spider. Researchers have combined three different manufacturing techniques to create a novel origami-inspired soft material microfabrication process that goes beyond what existing approaches can achieve at this small scale.... -
Video/AnimationHAMR: Robotic Cockroach for Underwater ExplorationsThis video shows how the HAMR can transition from land to water, paddle on the surface of water, or sink to the ground to start walking again just as it would on dry land.

Video/AnimationFLIPS: Ferrofluid-Containing Liquid-Infused Porous SurfacesAs a magnetic field is applied and moved, the ferrofluid component of FLIPS responds dynamically, allowing the surface to be endlessly reconfigured. Credit: Harvard SEAS -
Video/AnimationMeet HAMR, the Cockroach-Inspired RobotThe Harvard Ambulatory Microrobot - nicknamed HAMR - is a versatile robot that can run at high speeds, jump, climb, turn sharply, carry payloads and fall from great distances without being injured.
