Highly conformal tungsten nitride films for use in microelectronics and semiconductors
The invention describes a method of producing a uniform, smooth and conformal coating of tungsten nitride, synthesized by atomic layer deposition (ALD). The silver-colored coating (or film) is metallic and a good electrical conductor.

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…

Lead compounds for the treatment of pain
The invention is a novel synthetic pathway to the generation of nonpeptidic ligands for the mu opioid class of G-protein coupled receptors. The system uses stereochemical variation and acyclic geometric stereocontrol to generate diversity among its…

Modulating gene activity on chondrocytes
Transgenic mice were generated in which the regulatory sequences for the Col2a1 gene were used to drive expression of Cre recombinase in chondrocytes. The strain initiates Cre-mediated recombination predominantly in immature chondrocytes and the…

Drug-inducible RNA aptaswitch for regulating eukaryotic protein expression
Using in vivo evolution techniques, scientists in the Liu laboratory have engineered a drug-inducible aptaswitch for regulating eukaryotic protein expression at the transcription level. This aptaswitch consists of two modular RNA elements: a…

Animal model of diabetes and obesity
Mice with the JNK 1 and JNK2 genes knocked out were crossed with the obese mouse line (ob/ob) to create a mouse model of diabetes and obesity. These mice exhibit many of the hallmark metabolic pertubations characteristic in diabetes and obesity.

Monoclonal IgE anti-ovalbumin antibody
A laboratory from the Harvard School of Public Health has developed a monoclonal Ig E mouse anti-ovalbumin. This antibody is useful as a positive control in ELISA assays used to measure the level of IgE anti-ovalbumin antibodies in mouse models of…

Bead-based polymerase colony microarrays and nucleic acid sequencing ("Polony-FISSEQ Beads")
Foundational work of Dr. George Church has enabled the production and use of replicable arrays of polymerase-amplified nucleic acid colonies (so-called "polonies") on semisolid support matrices (see Harvard Case #1438). The present invention extends…

Modular conditional knockout: Precise temporal control of protein degradation in living cells
Polyubiquitinated proteins in eukaryotes are directed to the proteasome for degradation. It is generally accepted that proteasome-mediated proteolysis depends strictly upon ubiquitination, as disruption of that process has been observed to halt…
