Rapid characterization and quality control of complex cell culture media solutions using Raman spectroscopy and chemometrics
(2010)
The use of Raman spectroscopy coupled with chemometrics for the rapid identification, characterization, and quality assessment of Complex cell culture media components used for industrial mammalian cell culture was ...
Fluorescence EEM Spectroscopy for Rapid Identification and Quality Evaluation of Cell Culture Media Components.
(Ingenta, 2011-11)
The application of fluorescence excitation-emission matrix (EEM) spectroscopy to the quantitative analysis of complex, aqueous solutions of cell culture media components was investigated. These components, yeastolate, ...
Study of water adsorption in PolyN-isopropylacrylamide) thin films using fluorescence emission of 3-hydroxyflavone probes
(ACS Publications, 2010)
The noncontact measurement of water uptake in microscale , thermoresponsive poly(N-isopropylacrylamide) thin films is challenging. We assessed the efficacy of three different 3-hydroxyflavone (3-HF)-based fluorophores to ...
Prediction of Cell Culture Media performance using Fluorescence Spectroscopy
(ACS Publications, 2010)
Cell culture media used in industrial mammalian cell culture are complex aqueous solutions that are inherently difficult to analyze comprehensively. The analysis of media quality and variance is of utmost importance in ...
Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor
(2003)
We report a novel fluorescence-lifetime-based pH sensing method that utilizes acridine incorporated into Nation (AcNaf) as the fluorescent indicator. The AcNaf sensor is excited using a 380 nm light emitting diode (LED) ...
A stainless steel multi-well plate (SS-MWP) for high-throughput Raman analysis of dilute solutions
(Wiley, 2010)
The use of Raman spectroscopy for the qualitative and quantitative analysis of dilute aqueous solutions is of interest to the biopharmaceutical manufacturing sector. However, the inherent weakness of the Raman effect, ...
Prediction of cell culture media performance using fluorescence spectroscopy.
(American Chemical Society, 2010)
Cell culture media used in industrial mammalian cell culture are complex aqueous solutions that are inherently difficult to analyze comprehensively. The analysis of media quality and variance is of utmost importance in ...
Measuring the Micro-Polarity and Hydrogen-Bond Donor/Acceptor Ability of Thermoresponsive N-Isopropylacrylamide/N-tert-Butylacrylamide Copolymer Films Using Solvatochromic Indicators
(2009)
Thin polymer films are important in many areas of biomaterials research, biomedical devices, and biological sensors. The accurate in situ measurement of multiple physicochemical properties of thin polymer films is critical ...
Investigating tryptophan quenching of fluorescein fluorescence under protolytic equilibrium
(2009)
Fluorescein is one of most used fluorescent labels for characterizing biological systems, such as proteins, and is used in fluorescence microscopy. However, if fluorescein is to be used for quantitative measurements involving ...
Identifications and quantitative measurements of narcotics in solid mixtures using near-IR Raman spectroscopy and multivariate analysis.
(ASTM International, 1999)
Raman spectroscopy offers the potential for the identification of illegal narcotics in seconds by inelastic scattering of light from molecular vibrations. In this study cocaine, heroin, and MDMA were analyzed using near-IR ...
