Curriculum Vitae

Dr. Meikun Fan

Professor, Assistant Dean

Physical/Analytical Chemistry

Ph.D. University of Victoria, Canada (2010)

M.Sc. Southwest China Normal University (2002)

B.Sc. Southwest China Normal University (1999)

    

     Dr. Fan obtained his Master's degree in Southwest China Normal University in 2002, under the supervision of Dr. Chengzhi Huang. His thesis involved the developing of analytical methods for trace amount of analytes based on fluorescence spectroscopy using the famous coffee ring effect. 

     After receiving his degree, he then worked as a university lecturer in Dalian University of Technology in China. 

     In 2005, he joined Dr. Alexandre G. Brolo's group in University of Victoria in Canada, pursuing his Ph.D. degree. His project mainly focused on the fabrication, modification and self-assembly of metallic nanoparticles for surface enhanced vibrational spectroscopic and localized surface Plasmon resonance applications. During his study, he developed different SERS substrates to work in different environment with high sensitivity and reproducibility.  He also developed a localized SPR sensor for detecting biomolecules on common plastic.

     After finishing his Ph.D., he went to University of Western Ontario for a 6 months post-doctoral research.

     In March 2011, Dr. Fan moved back to Chengdu, China, and worked as associate research scientist and principal investigator of the lab of environmental science and technology in a company.  

     In June 2013, Dr. Fan joined in Southwest China Jiaotong University and was promoted to full professor at the Department of Environmental Science and Engineering.

     In 2015, he was nominated to the board of International Affair Committe of Southwest Jiaotong University. he was also appointed to assistant dean of the Faculty of Geosciences and Environmental Engineering.

    

Research Interests
   

1. Surface Enhanced Vibrational Spectroscopy

     Surface enhanced vibrational spectroscopy (SEVS), namely surface enhanced Raman scattering (SERS) and surface enhanced infrared absorption spectroscopy (SEIAS), as its name indicates, is a molecular vibrational spectroscopy enhanced by certain coinage metallic nanomaterials, such as gold, silver, and copper. There are many advantages in applying SEVS for chemical analysis. For example, SERS is known to be very sensitive, single molecule analysis has been widely reported in literature by the using of SERS. On top of sensitivity, SEVS also provides the fingerprint-like information of molecules, which helps the identification of analyte. In addition, the instruments, both Raman and infrared spectrometers, are capable of miniaturizing. Hence, researchers all around the world are working on this technique, developing methods for many applications, including biomedical, homeland security, and many other fields.

     We have specifically focused on the application of SEVS in environmental monitoring. We have 4 grants from national natural science foundation of China supporting the research in this direction, with a total budget of 2.1 million CNY.

     In the past, we tried to develop SERS Optrode, or SERS optical fiber sensor, for remote sensing. Later, we combine the Optrode with superhydrophobic surface to form analytical device for trace sample analysis. The SERS Optrode was used as the fishing hook to preconcentrate analyte on the surface of a superhydrophobic material. Recently, we shift our interest on surface contaminants, such as pesticides on fruit surfaces, and explosives on luggage. We proposed a shape adaptable hydrogel SERS substrate for this specific application.

     We are also working on SEIAS for bacteria sensing.

2. Imaging Based Environmental Monitoring

     COMS image sensor has been widely utilized in smartphone as well as DSLR cameras as the image acquiring device. It can also be used in analytical chemistry, for the acquiring of optical signal. Currently, the smartphone based sensing is mostly for point analysis, it is still difficult to acquire large amount of data simultaneously. On the other hand, hyperspectral imaging has become one of the main stream remote sensing technique in environmental survey. However, it still lacks the capability of detect accurate chemical pollutants information. We want to bridge the two techniques to provide instant and high throughput information of local pollution.

3. Point of Use pollution control materials

     This theme we aim to develop point of use water disinfection materials. In other words, we intend to develop novel materials to help people in resource limited countries and situations get clean and safe water.

4. Localized Surface Plasmon Resonance Analysis

     Point of care diagnostics will be one of the most important move in future healthcare development. When combined with internet, all data related to a patient can be collected instantly and transferred to a doctor. In such a way a care can be quickly provided to the patient. This is called modern telemedicine. In this theme we intend to develop sensors that can detect analytes that is clinically important, based on modern nano-technology.
