Vertical silicon nanowires as a universal platform for highly efficient delivery of bioactive molecules into living cells

This platform consists of an array of surface-modified vertical silicon nanowires that have been chemically grown or etched on a wafer and to which virtually any kind of bioactive species (drug, protein, nucleic acid, nanoparticles) may be attached…

Invention

Electrically-driven nanoscale lasers

This invention is the first demonstration of an electrically driven nanoscale laser. A CdS nanowire, comprising a Fabry-Perot cavity, in contact with an electrode distributed along its length or crossing a Si nanowire, lases above a threshold…

Invention

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,…

Oxygen-activated gold as a green catalyst for selective methoxycarbonylation

A group of Harvard scientists led by Profs. Madix and Friend has developed a catalyst based on gold for very selective production of dimethyl carbonate. The new process is environmentally friendly and its advantages are threefold. First, it starts…

Invention

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

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…

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…
