Distribution of chromosome 18 and X centric heterochromatin in the interphase nucleus of cultured human cells [PDF]

, 1990
In situ hybridization of human chromosome 18 and X-specific alphoid DNA-probes was performed in combination with three dimensional (3D) and two dimensional (2D) image analysis to study the interphase distribution of the centric heterochromatin (18c and ...

Achromatized endomicroscope objective for optical biopsy [PDF]

, 2013
Currently, researchers and clinicians lack achromatized endomicroscope objectives that are as narrow as biopsy needles. We present a proof-of-concept prototype that validates the optical design of an NA0.4 objective.

Adaptive optics retinal scanner for one-micrometer light source [PDF]

, 2010
We developed an adaptive optics (AO) retinal scanner by using a light source with a center wavelength of 1-microm. In a recent study on optical coherence tomography (OCT), it was proved that 1-microm light provided higher image contrast of deep region of

A method for assessing measurement precision and stability of optical probes [PDF]

, 2016
The current strategy for measuring non-specular metre-scale surfaces – for instance segmented freeform optics post-grinding – in the mid- frequency bandwidths (S-filter), involves the use of contact probe based systems where measurement precision is a ...

Wideband THz time domain spectroscopy based on optical rectification and electro-optic sampling [PDF]

, 2013
We present an analytical model describing the full electromagnetic propagation in a THz time-domain spectroscopy (THz-TDS) system, from the THz pulses via Optical Rectification to the detection via Electro Optic-Sampling.

Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels

Advanced Functional Materials, EarlyView.
Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...
