Single-Cell Proteomics Is in the Chips

July 28, 2015

At Northeastern University, researchers are developing ScanDrop, a lab-on-a-chip biosensor approach that utilizes a well-mixed microfluidic device and a microsphere-based assay capable of performing near real-time diagnostics. ScanDrop has [more...]

Microlasers Track Cells from the Inside

July 28, 2015

Artist rendering of a group of cells that have absorbed microlasers. The spectral composition of the laser light from each cell is different, which provides a barcode-type tag and enables reliable noncontact optical tracking of a large [more...]

Device Delivers Drugs to Brain Via Remote Control

July 20, 2015

A team of researchers has developed a wireless device the width of a human hair that can be implanted in the brain and activated by remote control to deliver drugs. The technology, demonstrated for the first time in mice, one day may be [more...]

Nanowire Yarns Supercharge Wearables

July 8, 2015

Yarn made of niobium nanowires, seen here in a scanning electron microscope image (background), can be used to make very efficient supercapacitors, MIT researchers have found. Adding a coating of a conductive polymer to the yarn (shown in [more...]

Review on Exosome Isolation: A Microfluidic Road-map

July 6, 2015

Ciliated structures for exosome isolation and capture by Wang et al. The hierarchical geometry of the device does not allow cells larger than 1 μm to access the wired area, due to the distance between the pillars (b) being too narrow (900 [more...]

Chemists Design A Quantum-dot Spectrometer

July 5, 2015

The Quantum Dot (QD) spectrometer device is printing QD filters — a key fabrication step. Other spectrometer approaches have complicated systems in order to create the optical structures needed. Here in the QD spectrometer approach, the [more...]
