Label-free mid-infrared photothermal microscopy revisits intracellular thermal dynamics: what do fluorescent nanothermometers measure?
Keiichiro Toda, Masaharu Takarada, Genki Ishigane +4
Fluorescent nanothermometry has revealed pronounced intracellular temperature heterogeneity, establishing the field of single-cell thermal biology. However, these observations have…
Mid-infrared wide-field nanoscopy
Miu Tamamitsu, Keiichiro Toda, Venkata Ramaiah Badarla +3
Mid-infrared (MIR) spectroscopy is widely recognized as a powerful, non-distractive method for chemical analysis. However, its utility is constrained by a micrometer-scale spatial…
Upconversion time-stretch infrared spectroscopy
Kazuki Hashimoto, Takuma Nakamura, Takahiro Kageyama +4
High-speed measurement confronts the extreme speed limit when the signal becomes comparable to the noise level. In the context of broadband mid-infrared spectroscopy, state-of-the-…
Mid-infrared photothermal single-live-cell imaging beyond video rate
Genki Ishigane, Keiichiro Toda, Miu Tamamitsu +3
Advancement in mid-infrared (MIR) technology has led to promising biomedical applications of MIR spectroscopy, such as liquid biopsy or breath diagnosis. On the contrary, MIR micro…
Label-free biochemical quantitative phase imaging with mid-infrared photothermal effect
Miu Tamamitsu, Keiichiro Toda, Hiroyuki Shimada +6
Label-free optical imaging is valuable in biology and medicine with its non-destructive property and reduced optical and chemical damages. Quantitative phase (QPI) and molecular vi…
