More than a quarter of SUTD faculty ranked top 2% of world’s best scientists for 2023
The prestigious list, as compiled by Stanford University, is based on the bibliometric information in the Scopus database and includes more than 220,000 researchers from across the globe, classified into 22 scientific fields and 174 subfields.
How to capture solar energy more efficiently
In a multi-institutional collaboration, one SUTD researcher finds a way to optimise the design of perovskite tandem solar cells using machine learning.
Sparking New Insights Into Dye Chemistry
The SUTD-led study leverages systematic design and molecular engineering to develop brighter, more sensitive fluorophores used in detection probes and imaging labels.
Fluorophores, a chemical compound that can emit light, can be used as fluorescent labels for bioimaging, and fluorescent probes to detect a wide range of chemical species and physical parameters.
During twisted intramolecular charge transfer (TICT) – a photophysical process that occurs in many fluorophores – fluorescence gets extinguished. The donor and acceptor fragments of the fluorophore will twist to a nearly perpendicular conformation after photoexcitation, resulting in complete charge separation while transforming into a dark state.

Using Quantum Parrondo’s Random Walks for Encryption
Assistant Professor Kang Hao Cheong and his research team from the Singapore University of Technology and Design (SUTD) have set out to apply concepts from quantum Parrondo’s paradox in search of a working protocol for semiclassical encryption. In a recent Physical Review Research letter, the team published the paper ‘Chaotic switching for quantum coin Parrondo’s games with application to encryption’ and discovered that chaotic switching for quantum coin Parrondo’s games has similar underlying ideas and working dynamics to encryption.

General Descriptor Sparks Advancements in Dye Chemistry
SUTD collaborates with international researchers to move away from inefficient trial-and-error developments in dye chemistry and quantitatively design luminescent materials.
Researchers from SUTD, DICP, and POSTECH developed a theoretical descriptor ΔE for predicting PET-based fluorescence probes; utilizing this descriptor, they quantitatively designed fluorescent stains of lipid droplets and mitochondria for live-cell bioimaging.
There is an ongoing demand in biological research to accelerate the development of fluorescent probes based on the photo-induced electron transfer (PET) mechanism. By modulating PET formations, these probes significantly change fluorescence intensities, allowing a convenient route to monitor analytes or environmental changes with high sensitivity, vivid visibility and excellent spatiotemporal resolution.

Illuminating the Path for Super-resolution Imaging with Improved Rhodamine Dyes
DUT and SUTD researchers 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.
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.
Recent years have witnessed a rapid evolution of advanced fluorescence imaging techniques, such as single-molecule localization microscopy (SMLM) that allows for unprecedented resolution beyond the Abbe diffraction limit of the optical microscope.
