July 2020 : We received the North Carolina Biotechnology Center Flash Grant Award!

This grant will be used to repurpose an optical diagnostic platform for acute phase identification of COVID-19 infections.

April 2020 : Allison Stadick is this year’s recipient of the ACS C-P Excellence in Undergraduate Research Award! Congrats, Allison!

Allison was recognized for her outstanding achievement on developing Gold-Silver Bimetallic Nanoparticles as a SERS Substrate for Optical Detection of RNA Biomarkers.  While the ACS C-P section will not be holding the Student Awards meeting this year, she will be recognized with a certificate and a monetary award. 

February 2020 : Dr. Indrasekara gave an invited talk at the SPIE-BIOS conference on “Bio-nano interface engineering for field-transferable biosensors“. She also chaired the session on “Nano-Bio Complexes and Assemblies“.

January 2020 : Casey Folks joins our lab as a graduate student and Mahima Rajesh as a new undergraduate researcher. Welcome to the team!

January 2020: We gathered at the Smelly Cat Coffee to get warmed up for the new year!


Oct 26th 2019 : The first conference presentations from our lab!We had a wonderful time attending and sharing our work at the 2019 North Carolina Photochemistry Symposium.

  • Allison Stadick, Thushara Arja & Logan Hamm presented their work on functional nanomaterials and assay development for ex vivo biosensing.
  • Dr. Indrasekara gave an invited talk on “Nanophotonics-enabled molecular analyses: From diagnostics to catalysis”.

August 2019 : Dr. Uttam Sharma joined our team as a postdoctoral associate. Allison Stadick and Bhavana Reddy are the new undergraduate researcher in our group. Welcome All!


July 12th 2019 : Logan Hamm is the 2019/20 Walsh Graduate Research Fellow. Congratulation!

The Thomas D. Walsh Graduate Research Fellowship is the most prestigious student award in the Department of Chemistry that recognizes and support excellence in graduate research in chemistry. This fellowship will support Logan for the 2019–2020 academic year. Great job, Logan!

May 28th 2019 : New REU students in the lab for summer 2019!

We welcome Joshua Taylor from North Carolina A&T and Michael Gladden from Winthrop University. Glad to have you around for the next 10 week in our lab!

May 10th 2019 : Logan received the best graduate teaching student award! Way to go Logan!

May 16th 2019 : Dr. Indrasekara and Dr. Fabris (Rutgers University) officially celebrated their first USA patent awarded in 2018!

Check out the details of our invention here. Fabris, L.; Indrasekara, A. S. D. S. US Patent No. US 10,024,800 B2 titled “Gold Nanostar Substrates for SERS Sensing in the Femtomolar Regime” published July 17, 2018

April 3rd 2019 : The first review paper from our group, “Recent Advancement in the Surface-Enhanced Raman Spectroscopy-Based Biosensors for Infectious Disease Diagnosis” is now online. Congrats Amira and Logan!

We highlight the progress on the SERS approaches towards bacterial & mosquito-borne infectious disease diagnosis in the last 10 yrs & where we should be heading next. Check our paper out here.

February 1st 2019 :We are beyond excited to moving into our new lab space!!

Thanks for everyone who showed up for our lab warming party. We are ready to do some cool science!!

January 2019 : The new year is off to a great start!

We are getting our new equipment delivered and installed. The new lab space is almost ready to move-in! We had extensive training sessions on using our new integrated confocal Raman and hyperspectral dark-field microscope. Can’t wait to play with these new toys!


October 12th 2018 Logan Hamm joined our group as a first year graduate student. Welcome Logan!

October 12th 2018:We had our first group meeting in Burson 113.

Amira shared her previous research experience while we all celebrated Madeline’s B’day! 

September 13th 2018: Amira Gee joined as the first graduate student of our lab. Welcome Amira!

September 13th 2018:We started our research out in an interim lab space.
