Laser-Induced Breakdown Spectroscopy vs. Fluorescence Spectroscopy for Olive Oil Authentication [PDF]

open access: yesFoods
In the present work, laser-induced breakdown spectroscopy (LIBS) and fluorescence spectroscopy are used and assessed for the detection of EVOOs’ adulteration with some non-EVOO edible oils (i.e., pomace, corn, sunflower, and soybean) and the ...

Remote Measurements of Tear Electrolyte Concentrations on Both Sides of an Inserted Contact Lens

open access: yesChemosensors, 2023
In this paper, a method is described to perform ion concentration measurements on both sides of an inserted contact lens, without physical contact with the eye or the contact lens. The outer surface of an eye is covered with a tear film that has multiple

Sawmill waste derived carbon dots as a fluorescent probe for synthetic dyes in soft drinks

open access: yesScientific Reports, 2021
Herein, for the first time the carbon dots (CDs) were synthesized by reflux method from sawmill waste material. We also represent a novel strategy based on fluorescent CDs for determination of ponceau 4R and allura red dyes in soft drinks. Interestingly,

Smartphone fluorescence spectroscopy [PDF]

open access: yesSPIE Proceedings, 2014
We demonstrate the first use of smartphone spectrophotometry for readout of fluorescence-based biological assays. We evaluated the smartphone fluorimeter in the context of a fluorescent molecular beacon (MB) assay for detection of specific nucleic acid sequences in a liquid test sample and compared performance against a conventional laboratory ...

Fluorescence correlation spectroscopy and fluorescence cross‐correlation spectroscopy [PDF]

open access: yesWIREs Systems Biology and Medicine, 2009
AbstractThis article focuses on methods based on fluctuation correlation spectroscopy to determine the formation of protein complexes in living cells. We present the principles of the fluctuation method applied to cells. We discuss the novelty and the promises of this approach. The emphasis is in the discussion of the underlying statistical assumptions
