Undergraduate Student Opportunities

The National Science Foundation has recently predicted that approximately 1 million jobs will be created in the Unites States nanotechnology sector. Over 80% of these employment opportunities will require training in nanotechnology and nanoscience. Unfortunately, very few schools offer such trainings at the undergraduate level.


The first NANOTECHNOLOGY AND NANOSCIENCE LABORATORY on campus will start in Fall 2012 semester and will be open to both undergraduate and graduate students from the College of Science and Mathematics and the College of Computer Science and Engineering. It will be team-taught by Dr. Ioana (Pavel) Sizemore, Dr. Steven Higgins, Dr. Jason Deibel and Dr. Hong Huang. All laboratory modules will be research-oriented and will make use of cutting-edge technologies and state-of-the-art instrumentation. This unique laboratory will be developed with the help of a grant from the National Science Foundation – Nanotechnology Undergraduate Education Program (NSF-NUE). Students interested in learning more about the course should contact any of the four faculties.


The Undergraduate Research Student PROJECT in my laboratories involves the synthesis, characterization, and applications of noble metal nanomaterials.
The undergraduate students will be responsible for various parts of the project according to their level of education and training. The undergraduate students will also be involved in the preparations of peer-reviewed research manuscripts and conference presentations.

Scientific Goals

1. To fabricate colloidal noble metal nanomaterials using bottom-up approaches
i) well-established wet-chemistry methods and
ii) alternative, energy-efficient methods involving one-pot reactions in a microwave digestor and generally regarded as safe (GRAS) and/or non-toxic, non-hazardous or antimicrobial/antioxidants reducing reagents.

2. To characterize the physical and chemical properties of the noble metal nanomaterials using a combination of cutting-edge technologies and state-of-the-art instrumentation
The physical and chemical properties of nanomaterials will be characterized using UV-VIS absorption spectrophotometry, X-Ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), surface area and porosity analysis, flame atomic absorption spectroscopy (FAAS), and inductively coupled plasma optical emission spectroscopy (ICP-OES). The tests will establish the elemental composition, purity, concentration, size and shape distribution, aggregation state, stability, and surface plasmon resonance of the noble metal nanomaterials. These properties are vital for various applications in our laboratories as they will determine the SERS scattering efficiency, dictate the cellular uptake, cytotoxicity, and antiviral/antimicrobial properties of the nanomaterials.

3. To demonstrate that these silver nanomaterials are capable of generating “hot spots” for SERS-based biosensing applications.
The biosensing efficiency of the noble metal nanomaterials will be estimated by calculating the analytical (AEF) and surface enhancement (SEF) factors of standard test probes (e.g., rhodamine 6G – R6G). Raman, SERS, and fluorescence spectroscopy measurements will be performed on each colloidal system.
