09 Feb 2025 - Congrats to Pengqing on the publication of an exciting work on a smart organic optoelectronic device that clearly visualizes weak near-infrared (NIR) light. By integrating photodetection, a light-emitting diode, and photovoltaic functions into a single platform, the device automatically boosts its upconverted emission whenever incoming NIR light falls below a preset threshold—ensuring reliable and enhanced visualization.  P.

19 Aug 2024 - Congrats Sherwin and Le that our outcome has been reported by The Straits Times -- NUS, A*Star researchers develop sensor that can detect cholesterol and glucose from skin Researchers from NUS and A*Star have developed a wearable, stretchable hydrogel-based sensor that non-invasively detects biomarkers—including cholesterol, lactate, and glucose—directly from the skin’s outer layer. The innovation promises a more comfortable and convenient method for monitoring chronic conditions such as diabetes and cardiovascular diseases, with potential integration into everyday wearables like smartwatches. 

18 Sep 2024 - Congratulations to Jiajia on publishing a paper introducing a novel method to enhance the visible electrochemiluminescence (ECL) of singlet oxygen (¹O₂), which is valuable for applications in biochemistry and material science. Using surface engineering on carbon electrodes, our team achieved a brighter, switchable ECL system with increased sensitivity for detecting tertiary amines. This work paves the way for more practical and portable ECL-based sensing and imaging technologies. J. Gao, Y. Yu, W. P. Goh, H. L. D. Seng, C. Jiang, L.

8 July 2024 - Congratulations to Pengqing on publishing a groundbreaking paper in solid-state infrared-to-visible photon up-conversion! The research introduces a novel bulk-heterojunction sensitizer that significantly improves efficiency to 2.20% at a low excitation intensity of 10 mW cm−2. This innovation paves the way for scalable, efficient up-conversion devices on flexible substrates. P Bi, T Zhang, Y Guo, J Wang, XW Chua, Z Chen, WP Goh, C Jiang, EE. M. Chia, J Hou & L Yang.

12 June 2024 - Congratulations to our former student Ruth Theresia Arwani that the new work has been published! We are excited to announce a breakthrough in health monitoring technology with the development of a new sensor capable of continuous and in situ detection of biomarkers directly from the skin. This innovative sensor employs an ionic–electronic bilayer hydrogel to seamlessly dissolve, diffuse, and electrochemically detect solid-state biomarkers such as lactate and cholesterol. 

31 May 2024 - Congratulations to our colleague Xian Wei! His work has just been published! In this work, mixed halide perovskite nanocrystals were utilized to transfer energy to triplet annihilators DPA and TIPS-An. The upconversion efficiency was five times higher in a composite system of both annihilators than with each individually. This highlights the potential of composite annihilators to boost TTA-UC, with applications in light-harvesting, imaging, sensing, therapeutics, and photocatalysis.

28 Feb 2024 - Our group had the honor of hosting distinguished researcher Prof. Mark E. Thompson. Renowned for his groundbreaking contributions to organic light emitting diodes, Prof. Thompson engaged in a productive exchange of ideas with our research group, fostering an environment of knowledge-sharing and innovation.
