Facilities

Office and Space

Dr Garcia's office is located in the third floor of Hunter Laboratories (# 363).

The laboratory occupies 1000 sp. ft. and is distributed in two laboratories (#201 and #236).

The chemistry department is housed in the Howard L. Hunter Chemistry Laboratory, which includes over 50,000 square feet of laboratory space for research and teaching. This building accommodates about 100 graduate students, postdoctoral scientists and visiting scientists. It includes a satellite chemistry library that houses the field’s most important journals and supplements extensive holdings in the University’s central library. Several chemistry research groups also occupy space in other on- and off-campus buildings.


Instrumentation in Dr. Garcia's Lab

Variable Angle Spectroscopic Ellipsometer (Woollam)
This instrument can measure changes in the thickness of substrates with a sensitivity of <1 nm and it is been used to elucidate the role of electrical stimulation on the adsorption of various proteins. You may check the following papers from the lab:
- Langmuir 31 (2015) 2455 – 2462 (PDF)
- Tissue Engineering, Part C: Methods 22 (2016) 69 - 75 (PDF)

Capillary Electrophoresis (PACE/MDQ Beckman Coulter) with UV detection
This instrument can perform highly efficient separations of analytes based on charge/mass ratios and it is been used to investigate oxidation processes, as a simple way to condition samples prior to the separation. We also use it to optimize the experimental conditions for our microfluidics work. Examples are:
- Analytical Chemistry 89 (2017) 1362 – 1368 (PDF)
- Electrophoresis 37 (2016) 2509 - 2516 (PDF)

IS400 Rotary Engraver (Gravograph) and CO2 Laser Engraver (EpilogMini)
These computer-controlled engravers are typically used to cut small parts and substrates fro our research projects. The laser engraver is a key instrument for the development of plastic and paper-based microfluidic devices. Publications linked to these instruments are:
- Analyst 142 (2017) 3899 - 3905 (PDF)
- Electrophoresis 35 (2014) 2325 - 2332 (PDF)

Linderberg Tube Furnace w/temperature and gas control
This furnace is currently hooked to a 5% hydrogen line and supports the preparation and characterization of nex-gen carbon materials. We have used this instrument to develop a variety of substrates based on pyrolyzed cellulose, for example
- Talanta 165 (2017) 33 - 38 (PDF)
- Analytical Methods 8 (2016) 4163 - 4176 (PDF)
