Instrumentation

We use a variety of advanced instruments maintained by the Chemistry department (including NMR, GC-MS, HPLC, XRD, spectroflurometer, capillary electrophoresis, and others); instruments at nearby Northwestern University, such as SEM, TEM, AFM and XPS; and the instruments in our own lab, detailed below:

Malven Zetasizer Nano ZS

Malven Zetasizer Nano ZS

Used for measuring the size and surface charge of nanoparticles.

Fluorescence microscope

Olympus IX81 inverted fluorescence microscope with Mightex Polygon 1000 patterning system

Used for photopatterning monolayers on surfaces, and observing fluorescent responses from them.

Jasco V750

Jasco V-750 UV/vis spectrophotometer

Used for measuring transmission spectra; equipped with a temperature-controlled, stirred 6-position automatic cell changer

Contact angle goniometer

Ossila contact angle goniometer

Used for measuring the hydrophobicity / hydrophilicity of surfaces, to characterize what the surface is coated with, the quality of the coating, and the cleanliness of the surface.

Nabertherm L 3/11 furnace

Reaches 1100 C. Used for forming gold nanoisland arrays.

Photocatalysis box

Custom built. Used for conducting photocatalysis experiments using 532 nm and 365 nm light.

UZ ozone cleaner

Ossila UV/ozone cleaner

Used for cleaning surfaces in preparation for coating with functional monolayers.
