BODIPY dyes have recently attracted attention as potential photosensitizers. In this work, commercial and novel photosensitizers (PSs) based on chromophores (haloBODIPYs orthogonal dimers strategically designed with intense bands in the blue, green or red region of visible spectra high singlet oxygen production) were covalently linked to mesoporous silica nanoparticles (MSNs) further functional...

The objective of this study was to determine the effect of different levels of dietary methionine on selected immune parameters of young turkeys. A total of 357 one-day-old female Hybrid Converter turkeys were randomly divided into three groups with low, medium and high level of dietary me- thionine (LM, MM, HM) of seven replicates each. Methionine was added to the basal diet (LM) at 0.16% (MM)...

BACKGROUND Investigations following stroke first of all require information about the spatio-temporal dimension of the ischemic core as well as of perilesional and remote affected tissue. Here we systematically evaluated regions differently impaired by focal ischemia. METHODOLOGY/PRINCIPAL FINDINGS Wistar rats underwent a transient 30 or 120 min suture-occlusion of the middle cerebral artery ...

Surface-enhanced Raman scattering (SERS) is a powerful technique that provides fingerprint vibrational information with ultrahigh sensitivity. However, only a few metals (gold, silver and copper) yield a large SERS effect, and they must be rough at the nanoscale. Shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) was developed to overcome the long-standing materials and morpholog...

This study reports on the first example, to our knowledge, of the usefulness of an ultrasound (US)-irradiation during an enzyme adsorption step, for enhancing the performance of a redox-enzyme-based amperometric biosensor. Horseradish peroxidase (HRP) and thionine (Th) were coadsorbed from a mixed aqueous solution of HRP and Th onto a carbon-felt (CF) under US-irradiation for 5 min with an ultr...

In this work, a novel sandwich-type aptasensor was designed for the ultrasensitive recognition of trace mercury ions in water. Numerous oriented platinum nanotube arrays (PtNAs) were in-situ crystallized on a flexible electrode as a sensing interface, while thionine labelled Fe3O4/rGO nanocomposites as signal amplifiers. Both PtNAs/CF and nanocomposites were synthesized by easy hydrothermal pro...
