Paper-supported 3D cell culture for cell and tissue-based bioassays

In this new approach, cells are cultured in 3D on a paper scaffold by adding a hydrogel precursor, as a fluid containing suspended cells, to a paper support, allowing the cell-containing fluid to distribute through the paper by capillary wicking,…

Bubble expansion of homogeneous epoxy suspensions of nanowires and carbon nanotubes to produce large area films

The invention describes a general and scalable, low temperature method involving bubble expansion of homogeneous epoxy suspensions of nanowires and carbon nanotubes to produce large area films. The nanowires and carbon nanotubes are well aligned in…

Invention

Improved performance of copper interconnects

Copper (Cu) is now the preferred material for interconnections in ICs because it conducts better and lasts longer than aluminum. However, there are well-known problems with copper interconnects. Copper tends to migrate out of the wiring, degrading…

Invention

Probing a living cell through a nanotube

The hybrid nanoscale system developed by Prof. Lieber’s team provides a unique approach for recording intracellular electrical signals. The system consists of a hollow nanotube, which serves as a probe, and a Si nanowire based field-effect…

Invention

Improved amide synthesis using silver as a catalyst

The Madix and Friend laboratories have developed a novel amide synthesis that uses metallic silver or silver-based alloy with oxygen adsorbed on the surface to catalyze the reaction of primary or secondary amines with alcohols or aldehydes. The…

Cyborg tissue: Macroporous nanowire nanoelectronic scaffolds for synthetic tissues

This technology uses macroporous, flexible and free-standing nanowire nanoelectronic scaffolds (nanoES), and their hybrids with synthetic or natural biomaterials. 3D macroporous nanoES mimic the structure of natural tissue scaffolds. The structures…

Control over deposition of nanoscale materials using structured surfaces

The ability to precisely localize and control deposition of materials at the nanoscale is extremely important for a wide variety of emerging technologies. Many unique physical properties emerge only at the nanoscale and it is very useful to be able…
