Our lab has a suite of equipment for nanoparticle synthesis, characterization, sample preparation, and near-infrared imaging. We welcome requests for researchers to use the following equipment.
Near-Infrared Single-Particle Imaging Microscope
721 nm 500 mW and 635 nm 300 mW excitation lasers, co-aligned into the same excitation path. 20x, 40x, 63x, and 100x objectives for excitation, with several filter cubes with long-pass emission filters. Imaging path can be directed to a brightfield Zeiss axiocam, or a Princeton Instruments NIRVana 640 InGaAs array to image wavelengths in the 900 nm – 1400 nm range.

Emission is aligned into a Princeton Instruments IsoPlane 320 and coupled to a liquid nitrogen-cooled Princeton Instruments PyLoN-IR 1D array of InGaAs pixels.
Beckman Coulter Delsa Nano C – Zeta potentiometer and DLS
The DelsaNano series uses photon correlation spectroscopy (PCS) to determine particle size by measuring the rate of fluctuations in laser light intensity scattered by particles as they diffuse through a fluid. The DelsaNano also performs charge measurements via size analysis and/or electrophoretic light scattering (ELS) to determine electrophoretic movement of charged particles under an applied electric field from the Doppler shift of scattered light, for zeta potential determination.
Shimadzu UV-3600 Plus
A UV-Vis-NearIR spectrophotometer with three detectors: a PMT for UV and visible wavelength detection, and an InGaAs and cooled PbS detector for long-wavelength detection. The spectrophotometer has a double monochromator with a wavelength range of 185 to 3300 nm.
Tecan Infinite M1000 Pro
Monochromator-based microplate fluorescence reader with 230 nm – 850 nm excitation wavelength selection and 280 – 850 nm emission measurement capabilities. Magellan software enabled.
Hydrofarm Plant Growth Chamber
Hydroponic or soil-based plant growth chamber with controllable light/dark cycles. We routinely grow spinach, arugula, and arabidopsis thaliana.
Beckman Coulter High-Performance Centrifuge
A model Avanti J-301 centrifuge with a fixed-angle rotor. Maximum speeds attained are 30,000 rpm and forces up to 100,000 g.
