Detection of vancomycin resistance in Enterococcus faecium and Enterococcus faecalis via cell wall
Technology The technology reveals cell wall remodeling dynamics with the innovative design of peptide molecules that mimic the structures of enzymes that are directly involved in peptidoglycan biosynthesis and direct indicators of vancomycin resistance enterococcus (VRE). The primary mechanism of action for vancomycin is to prevent cell wall synthe...

All Dimensional Continuous Fabrication
SUMMARY Three-dimensional printers currently in the market generally operate in a top-down additive process in which a printer head, constrained to move in a flat plane (by a two-dimensional stage), dispenses a plastic material onto a build surface. To enable three-dimensional formation of the plastic material, the building surface traverses in a d...

A Microfluidic Device with Microscale Wavy Pattern for Efficient Capturing of Circulating Tumor Cells
SUMMARYLehigh University has developed a wavy micropatterned microfluidic device for capturing circulating tumor cells from whole blood with high efficiency, selectivity and throughput. A capturing agent is immobilized on the substrate that can selectively capture circulating tumor cells while not interacting with other cells present in the whole b...

Engineered Crystallization of Atomic Layer Deposited Amorphous Metal Oxides
SUMMARYLehigh University has developed low-cost but high quality crystalline substrates and coatings of metal oxides. These substrates could be a replacement for other, more expensive coatings and substrates such as single crystal sapphire (aluminum oxide). Anytime an inorganic semiconductor is used it must be grown on a high crystalline quality s...

New Reagents for C4F8 Transfer that Eliminates the Use of Hazardous C2F4
SUMMARYLehigh University has developed new (perfluoroalkyl)metallacyclic zinc reagents that could be used in applications to transfer sequential difluoromethylene groups to organic, inorganic, and organometallic substrates. The accompanying methods to prepare the new zinc reagents have also been developed by the university. Known synthetic routes ...

Autothermal Cycle for Co2 Capture
SUMMARY Lehigh University has developed a novel process for carbon capture. This process removes carbon dioxide from flue gas through beds containing adsorbent materials. Desorption is performed by passing steam through the beds creating a stream of carbon dioxide mixed with steam. This mixture is then compressed to condense the steam and move the ...
