Rapid, Multi-Sample Assay of Gabapentin in Capsules Using Easy-to-Setup and Low-Cost Smartphone-Based Fluorescence Measurement [PDF]

open access: yesPharmaceutical Sciences
Background: Pharmacopeial methods for the quantification of gabapentin (GBP), particularly high-performance liquid chromatography (HPLC), require costly instrumentation, unsafe solvents in mobile phase, and time-consuming procedures.

Patch-Clamp Fluorometry: Electrophysiology meets Fluorescence [PDF]

open access: yes, 2014
Ion channels and transporters are membrane proteins whose functions are driven by conformational changes. Classical biophysical techniques provide insight into either the structure or the function of these proteins, but a full understanding of their ...

Digital Image Analysis of Actinomycetes Colonies as a Potential Aid for Rapid Taxonomic Identification [PDF]

open access: yes, 2010
High frequency isolation of actinomycetes poses a challenge for the taxonomists hence simple and rapid identification methods are required. Our work to catalogue biodiversity of actinomycetes of Goa yielded several distinct morphotypes.

Analysis of total urinary catecholamines by liquid chromatography: methodology, routine experience and clinical interpretations of results [PDF]

open access: yes, 1983
A simple routine method is described for simultaneous assay of total urinary adrenaline, noradrenaline and dopamine. The catecholamines are pre-purified on a small ion-exchange column, separated by reversed phase ion-pair liquid chromatography, and are ...

Light Stress Responses by the Eelgrass, Zostera marina (L)

open access: yesFrontiers in Environmental Science, 2018
Zostera marina is the dominant seagrass species in the Northern Hemisphere where it grows in sheltered bays and estuaries. As a consequence of its distribution its conservation is commonly threatened by poor coastal water quality.

Mesurment Instrument of Quantitative Fluorometry Intensity Based on Stoke’s Shift [PDF]

open access: yes, 2011
Mechanism of fluorescence stoke’s shift is discussed in detail in this paper. Optical wavelength of pumping laser is determined based on stoke’s shift, which puts forward the theory foundation of film-coating technology.

Synergistic Interaction between Anionic and Nonionic Surfactant: Application of the Mixed Micelles Templates for the Synthesis of Silver Nanoparticles

open access: yesInternational Journal of Electrochemical Science, 2016
Interaction between the anionic and nonionic surfactant at bulk and air/water interface has been studied. The synergistic interaction between surfactants was found in both in bulk solution as well as the interface.
