Clinical performance evaluation of total protein measurement by digital refractometry and characterization of non-protein solute interferences

open access: yesPractical Laboratory Medicine, 2016
Objectives: Refractometric methods to measure total protein (TP) in serum and plasma specimens have been replaced by automated biuret methods in virtually all routine clinical testing.

Refractometry of microscopic objects with digital holography

open access: yes, 2004
Digital holography has some desirable properties for refractometry of microscopic objects since it gives phase and amplitude information of an object in all depths of focus from one set of exposures.

Use of clinic refractometer at farm as a tool to estimate the IgG content in goat colostrum

open access: yesJournal of Applied Animal Research, 2018
Refractometry has been proposed as a farm technique to estimate the IgG concentration in colostrum. In order to validate the method in goat colostrum using a clinical refractometer, 216 colostrum and milk samples were obtained from 54 dairy goats ...

Fourier-Transform-Based Metrology for Whispering Gallery Mode Spectra in Soft Photonic Microcavities

open access: yesMetrology
We present a Fourier-transform (FT)-based framework for quantitative analysis of whispering gallery mode (WGM) spectra in soft photonic microcavities. By treating the WGM spectrum as a quasi-periodic signal, the method enables robust extraction of the ...

Estimate of colostral immunoglobulin G concentration using refractometry without or with caprylic acid fractionation

open access: yes, 2012
Our objectives were to evaluate the use of refractometry as a means of estimating immunoglobulin G (IgG) concentration of bovine maternal colostrum (MC) and determine if fractionation of MC using caprylic acid (CA) improved estimates of IgG. Samples (n =

Bifocal-optical coherenc refractometry of turbid media

open access: yes, 2003
We propose and demonstrate a novel technique, which we term bifocal optical coherence refractometry, for the rapid determination of the refractive index of a turbid medium.

Capillarity-driven (self-powered) one-dimensional photonic crystals for refractometry and (bio)sensing applications

open access: yes, 2014
In this work, we advance the state-of-the-art knowledge on photonic crystals by demonstrating the effective and reliable operation of vertical one-dimensional photonic crystals by capillarity, i.e.
