Molecular oxygen, O2, has long provided a cornerstone for studies in chemistry, physics,
and biology. Although the triplet ground state, O2 (X3Σg–), has garnered much attention, the …

Photoinduced reactions play an important role in the photocycle of fluorescent proteins from
the green fluorescent protein (GFP) family. Among such processes are photoisomerization …

In this Perspective we discuss recent trends in the development and applications of
fluorescent proteins. We start by providing a historical and structural perspective of their …

Consumer awareness on the side effects of chemical preservatives has increased the
demand for natural preservation technologies. An efficient and sustainable alternative to …

The genetically encodable fluorescent tag miniSOG is expected to revolutionize correlative
light-and electron microscopy due to its ability to produce singlet oxygen upon light …

Singlet oxygen, O2 (a1Δg), plays a key role in many processes of cell signaling. Limitations
in mechanistic studies of such processes are generally associated with the difficulty of …

UVA irradiation (320–400 nm) comprises about 95 percent of incident midday solar
ultraviolet irradiation. It penetrates skin much deeper than UVB irradiation. The absorption of …

Photobleaching, the irreversible photodestruction of a chromophore, severely limits the use
of fluorescent proteins (FPs) in optical microscopy. Yet, the mechanisms that govern …

The effect of the protein environment on the electronic structure of the green fluorescent
protein (GFP) chromophore is investigated by QM/MM (quantum mechanics/molecular …

Photoinduced electron transfer in fluorescent proteins from the GFP family can be regarded
either as an asset facilitating new applications or as a nuisance leading to the loss of optical …
