Shine on: A new rationaldesign strategy for near‐infrared‐emitting fireflyluciferins that are available in vivo has been developed using intramolecular bioluminescence resonance energy transfer (BRET). The emission wavelength could be freely tuned by the choice of BRET acceptor, and NIR bioluminescence could be detected in living cells and mice without the need for luciferase manipulation.
A detectable substrate for aldehyde dehydrogenase (ALDH) can be used for selecting cells that express ALDH. The detectable substrate can have a fluorescent moiety that has an excitation wavelength, an emission wavelength, or both, that does not overlap with the excitation wavelength, emission wavelength, or both, of green fluorescent protein.

ring of vitamin B12 is unable to efficiently absorb light beyond 550 nm, it is shown that commercially available fluorophores can be used as antennas to capture long‐wavelength light to promote scission of the CoC bond at wavelengths up to 800nm. The ability to control the molecular properties of bioactive species with long visible and near‐IR light has implications for drug delivery, nanotechnology
尽管维生素 B 12的 corrin 环无法有效吸收 550 nm 以上的光,但表明市售荧光团可用作天线来捕获长波长光,以促进波长高达 800的 Co C 键断裂纳米。利用长可见光和近红外光控制生物活性物质分子特性的能力对药物递送、纳米技术和细胞行为的时空控制具有重要意义。

There is provided a glucose-PEG conjugate comprising a PEG moiety conjugated to a linear glucose moiety at the C1 position of the glucose moiety. The glucose-PEG conjugate may be used to reduce glucose transport into a cell and may be used to treat a proliferative disorder.
