Advances in Optical Imaging and Photon Migration.
Confocal microscopy has become a standard technique for high resolution optical imaging in many fields1,2. Confocal imaging is conventionally limited to relatively transparent specimens, since image contrast is degraded by light scattering in turbid

The isotropic and linear dichroic triplet−singlet difference spectra of the Fenna−Matthews−Olson (FMO) complex of the green sulfur bacterium Prosthecochloris aestuarii measured with absorbance detected magnetic resonance (ADMR) are presented. T

Absorbance-detected magnetic resonance (ADMR) triplet−singlet difference (T−S) spectra are often measured with unpolarized light. We show that under nonsaturating conditions ADMR spectra are a func...

Linear and circular dichroic triplet-minus-singlet spectroscopy (LD(T-S) and CD(T-S)) are highly sensitive methods for determining the angles between the optical and microwave transition moments, the strength of molecular interactions, and band assig

The interaction between the light-harvesting antenna (LH1) and the reaction center (RC) in the photosynthetic purple bacteria Rhodobacter sphaeroides R26 and strain 2.4.1 was studied with low-temperature (1.5 K) absorbance-detected magnetic resonance

The carotenoid triplet states in the light-harvesting complex B800–850from purple bacterium Rubrivivax gelatinosus were characterized by absorption-detected magnetic resonance in zero magnetic field (ADMR) spectroscopy. Detailed HPLC analysis of ca

We describe a novel technique, based on optical coherence tomography, for enhanced optical sectioning in confocal microscopy. Confocal imaging deep into highly scattering media is demonstrated and compared with the predictions of a single-backscatter

We present laser flash-induced triplet-minus-singlet (TmS(flash)) and absorbance-detected-magnetic-resonance (TmS(ADMR)) measurements on the light-harvesting chlorophyll a/b pigment-protein complex (LHCII) from pea. We investigated the influence of L
