Abstract:: Intracellular pH (pH(i)) imaging is of paramount importance for life sciences. In this work, we implement the ultrafast electronic and stimulated Raman spectroscopies to unravel the fluorescence mechanism of an excitation-ratiometric pH(i) indicator in basic aqueous solution. After photoexcitation of the pH(i) indicator HPTS, a hidden charge-transfer (CT) state following...

Abstract:: Biosensors have become an indispensable tool set in life sciences. Among them, fluorescent protein-based biosensors have great biocompatibility and tunable emission properties but their development is largely on trial and error. To facilitate a rational design, we implement tunable femtosecond stimulated Raman spectroscopy, aided by transient absorption and quantum calculations,...

Creator:: Chen, Cheng, Zhu, Liang-dong, and Fang, Chong
Abstract:: Resonance enhancement has been increasingly employed in the emergent femtosecond stimulated Raman spectroscopy (FSRS) to selectively monitor molecular structure and dynamics with improved spectral and temporal resolutions and signal-to-noise ratios. Such joint efforts by the technique- and application-oriented scientists and engineers have laid the foundation for exploiting the tunable FSRS...

Abstract:: We strategically modified the GFP core via chemical synthesis to make redder and brighter biomimetic fluorophores. Based on quantum calculations, solvatochromism analysis, and femtosecond Raman, we unveiled the additive effect of tuning the electronic ground and excited states, respectively, to achieve a dramatic emission redshift with a "double-donor-one-acceptor" structure.

Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is an emerging molecular structural dynamics technique for functional materials characterization typically in the visible to near-IR range. To expand its applications we have developed a versatile FSRS setup in the ultraviolet region. We use the combination of a narrowband, ~400 nm Raman pump from...

Creator:: Tang, Longteng, Zhu, Liangdong, Taylor, Miles A., Wang, Yanli, Remington, S. James, and Fang, Chong
Abstract:: Tracking vibrational motions during a photochemical or photophysical process has gained momentum, due to its sensitivity to the progression of reaction and change of environment. In this work, we implemented an advanced ultrafast vibrational technique, femtosecond-stimulated Raman spectroscopy (FSRS), to monitor the excited state structural evolution of an engineered green...
