Resources

We use a number of research tools in our work. If you are located on campus and interested in using this equipment/resources, please contact us for availability and training.

 

Wet chemistry labs

 

Our wet chemistry labs are equipped for small molecule, polymer, and nanoparticle synthesis (hoods, vacuum lines and manifolds, sonicators, convection ovens, rotovaps, and a laboratory microwave system). We also have basic equipment for molecular biology and microbiology (including electrophoresis cells and high voltage power sources, UV illuminators, thermocyclers, centrifuges, shakers, rockers, refrigerators, -20° C freezer, controlled temperature incubator, DI water system and autoclave, UV cross-linking equipment, and digitally controlled probe ultrasonicator).

Custom DNA synthesis is done on ABI 392 DNA synthesizer. Shimadzu BioSpec-Nano UV-Vis spectrometer is used in analysis and quantification of 1-2 mL samples.

 

Surface chemistry

 

For surface modification and characterization, the lab is equipped with plasma cleaning system, contact angle goniometers, variable temperature tensiometer. We use variable angle spectroscopic ellipsometer for measurement of optical properties and thicknesses of thin films, including in situ biomolecular binding studies using flow-through fluid cells.

Chemistry department maintains angle resolved XPS facilities.

 

Microfabrication facilities

 

We use Lehigh’s Smith Family Center for Optical Technology (COT) to carry out our microfabrication work. COT contains equipment for microfabrication through conventional lithography: laminar flow hoods, spin coaters, mask aligners, reactive ion etching system, e-beam metal evaporator, and CVD systems.

Chemistry department maintains a glass blowing shop and a machine shop with a personal CNC system.

 

Imaging

 

The lab houses a combined TIRF–AFM system and assorted fluorescent microscopes equipped with CCD cameras (including EM-CCD) and a stereomicroscope.

Lehigh electron microscopy facility (at the Center for Advanced Materials and Nanotechnology) houses nine scanning and transmission electron microscopes, as well as an FIB system.
