Optical nanoparticle sorting elucidates synthesis of plasmonic nanotriangles
(American Chemical Society, 2016-02)
We investigate the optical and morphological properties of gold nanoparticles grown by reducing a gold salt with Na2S. Lasers are tuned to the observed plasmon resonances, and the optical forces exerted on the nanoparticles ...
Size-Selective Optical Printing of Silicon Nanoparticles through Their Dipolar Magnetic Resonance
(American Chemical Society, 2019-04)
Silicon nanoparticles possess unique size-dependent optical properties due to their strong electric and magnetic resonances in the visible range. However, their widespread application has been limited, in comparison with ...
Fluorescent silica nanoparticles with chemically reactive surface: Controlling spatial distribution in one-step synthesis
(Academic Press Inc Elsevier Science, 2017-06)
The encapsulation of fluorescent dyes inside silica nanoparticles is advantageous to improve their quality as probes. Inside the particle, the fluorophore is protected from the external conditions and its main emission ...
Sperm sexing mediated by magnetic nanoparticles in donkeys, a preliminary in vitro study
(Elsevier Science Inc, 2018-06)
Preselection of sex before conception has been one of the objectives pursued by scientists and breeders for many years. The donkey milk industry has shown a greater commercial interest, since jennies’ demand is increasing ...
Resolving Material-Specific Structures within Fe3O4/gamma-Mn2O3 Core/Shell Nanoparticles Using Anomalous Small-Angle X-ray Scattering
(American Chemical Society, 2013-01)
Here it is demonstrated that multiple-energy, anomalous small angle X-ray scattering (ASAXS) provides significant enhancement in sensitivity to internal material boundaries of layered nanoparticles compared with the ...
Improvement of bovine semen quality by removal of membrane-damaged sperm cells with DNA aptamers and magnetic nanoparticles
(Elsevier Science, 2016-07)
In cattle, cryopreservation of semen and sex-sorting kill up to 50% of spermatozoa and decrease the success of assisted insemination (AI). Therefore, significant efforts are being carried out to improve the quality of semen ...
Silac-based quantitative proteomic analysis of Lactobacillus reuteri CRL 1101 response to the presence of selenite and selenium nanoparticles
(Elsevier Science, 2019-03)
Stable isotope labeling in cell culture (SILAC) was applied for the first time on a lactic acid bacterium strain (L. reuteri CRL1101) for analyzing differential protein expression associated to selenite(Na 2 SeO 3 ) and ...
Identification, localization, and quantification of neuronal cell membrane receptors with plasmonic probes: Role of protein kinase D1 in their distribution
(American Chemical Society, 2014-09)
Detecting, imaging, and being able to localize the distribution of several cell membrane receptors on a single neuron are very important topics in neuroscience research. In the present work, the distribution of metabotropic ...
