An engineered pill (aka lab-on-a-pill) for spatial sampling of microbiome and other contents in the gut
SUMMARYTufts researchers have developed a device which traverses the gut and collects samples of the microbiome in a way that permits correlation of samples with particular locations from which they were sampled.BACKGROUNDMore than 1,000 species of bacteria inhabit the healthy gut. The vast majority of these bacteria have a beneficial, supportive role...

Flexible Parylene Metamaterials
BACKGROUNDTerahertz radiation is useful for a variety of applications. For example, because of its ability to penetrate most clothing, terahertz radiation provides a way to detect concealed weapons. Because of its ability to detect differences in water content and density of tissue, terahertz radiation can be used to reliably distinguish between normal...

Metamaterial / pHEMT Hybrid Devices for Terahertz Sources, Modulators and Detectors
BACKGROUNDBetween the optical frequencies and the microwave frequencies is a broad expanse of spectrum in the terahertz range. However, development of devices for operation in the terahertz range is hampered, to some extent, by a dearth of devices for manipulating or detecting terahertz waves.Terahertz radiation is useful for a variety of purposes,...
