Illuminating the Path for Super-Resolution Imaging with Improved Rhodamine Dyes

By collaborating with Professor Xiao Yi’s group from the Dalian University of Technology, we have developed a new strategy that enhances the brightness and clarity of sub-cellular structures when dyed with novel rhodamine fluorophores, laying the ground for the advancement of super-resolution microscopes.

This work was published in JACS, and covered by various medium, such as:

Congratulations to Chao and Weijie!

Researchers from DUT and SUTD developed a new class of quaternary piperazine-substituted rhodamines with outstanding quantum yields (Φ = 0.93) and superior brightness (ε × Φ = 8.1 × 104 L·mol-1·cm-1), for imaging cell membranes and lysosomes in biological cells with super-resolution microscopy.

Hiking at the Southern Ridges

On 17 November 2019, we hiked along the Southern Ridges. Starting from Harborfront, we went through Henderson Waves (which is the highest pedestrian bridge in Singapore) and enjoyed the tropical nature and city view in Singapore along the way. Finally, this trip has to end up with a scrumptious dinner with chili crabs as well as other local cuisines!

SUTD co-hosted Singapore Junior Chemistry Olympiad 2019

SUTD hosted >400 students from secondary schools in Singapore, during the Singapore Junior Chemistry Olympiad on 18 May 2019.

It is for the first time that Chemistry Olympiad came to SUTD.

During this event,  members of the Fluorescence Research Group played an instrumental role in setting up the venues and helping with the logistics. Thank you, guys!

We also appreciate all the great support provided by various departments of SUTD.

Twisted Intramolecular Charge Shuttle (TICS) in the News

Our work on Twisted Intramolecular Charge Shuttle (TICS) has been featured in SUTD Research News and reported in various media, such as:


Figure 1. (a) Schematic illustration of the twisted intramolecular charge shuttle (TICS) mechanisms; “D” and “A” denote electron-donating and electron-accepting fragments, respectively. (b) Reaction mechanism of a TICS based GSH fluorescent probe, and confocal microscope images of HeLa cells stained with the probe and Hoechst 33342 (a nucleus stain with blue emissions). No red emissions were observed in cells that were pre-treated with 1 mM NMM to remove GSH, while intense red fluorescence was present in cells with GSH. Scale bar = 20 μm.

Congratulations for the acceptance of Weijie’s paper by Angew. Chemie.

Families of the Fluorescence Research Group gathered at Chinatown for a sumptuous dinner in Mar 2019, to celebrate the acceptance of Weijie’s paper “Photoexcitation Induced Twisted Intramolecular Charge Shuttle (TICS)” by Angew. Chemie.

Congratulations, Weijie! And thank you, our collaborators from Professor Zhaochao Xu’s, Professor Young-Tae Chang’s, and Professor Matthew J. Lang’s groups.

Dr. Liu was elected as the Council Member of Singapore National Institute of Chemistry

Members of the Fluorescence Research Group attended the 50th Annual General Meeting (AGM) and Golden Jubilee Celebration Dinner of the Singapore National Institute of Chemistry (SNIC) on 29 Mar 2019.  “SNIC was established in March 1970 as a national body for the chemical profession in Singapore.”

During this AGM, Dr. Xiaogang Liu was elected as a Council Member of SNIC. We are excited to bring SUTD into the chemistry community in Singapore and look forward to learning from and working with our peers.

Dr. Dai Liang visited the Fluorescence Research Group.

Dr. Dai Liang from the Department of Physics at the City University of Hong Kong visited us in Jan 2019. Dr. Dai was an expert in multi-scale modeling, and we had a fruitful discussion on combining quantum chemical calculations and molecular dynamics to understand the photophysics and photochemistry of small molecule fluorescent dyes.

Welcome New Group Members

The Fluorescence Research Group welcomes its new members: Dr. Ying GAO (Visiting Researcher) and Dr. Chao WANG (Research Fellow).

We welcomed our members with a hot-pot lunch in a hot country. We also look forward to delivering good research results with teamwork and having lots of fun in 2019.

FB3 conference in Glasgow, UK

Dr. Liu attended the conference of Fluorescent Biomolecules and their Building Blocks (FB3), held in Glasgow, UK from Sat 30th June to Tue 3rd July, 2018.

He gave a talk on combining chemical “big data” and quantum chemical calculations to understand the structure-property relationships of fluorescent dyes.

He was very impressed by friendly Scottish people and the historical architectures in Glasgow.

He also visited the University of Glasgow, looking for student exchange opportunities for the undergraduate students at SUTD.
