In situ sensor techniques in modern bioprocess monitoring

22-Jul-2011 | Applied Microbiology and Biotechnology, 2011

Abstract New reactor concepts as multi-parallel screening systems or disposable bioreactor systems for decentralized and reproducible production increase the need for new and easy applicable sensor technologies to access data for process control. These sophisticated reactor systems require ...


Skull Flexure as a Contributing Factor in the Mechanism of Injury in the Rat when Exposed to a Shock Wave

07-Jul-2011 | Annals of Biomedical Engineering, 2011

Abstract The manner in which energy from an explosion is transmitted into the brain is currently a highly debated topic within the blast injury community. This study was conducted to investigate the injury biomechanics causing blast-related neurotrauma in the rat. Biomechanical responses of ...


Influence of Particle Size on the Ultraviolet Spectrum of Particulate-Containing Solutions: Implications for In-Situ Concentration Monitoring Using UV/Vis Fiber-Optic Probes

04-Mar-2011 | Bernard Van Eerdenbrugh, David E. Alonzo, Lynne S. Taylor, Pharmaceutical Research, 2011

ABSTRACT Purpose To critically evaluate the effect of submicron and micron-sized organic particulates on the ultraviolet (UV) absorption spectra of aqueous systems and assess the applicability of UV/Vis fiber-optic probes for in-situ concentration monitoring in the presence of particles of ...


Sequential Array Cytometry: Multi-Parameter Imaging with a Single Fluorescent Channel

06-Dec-2010 | Daniel R. Gossett, Westbrook M. Weaver, Noor S. Ahmed, Dino Di Carlo, Annals of Biomedical Engineering, 2010

: Heterogeneity within the human population and within diseased tissues necessitates a personalized medicine approach to diagnostics and the treatment of diseases. Functional assays at the single-cell level can contribute to uncovering heterogeneity and ultimately assist in improved treatment ...


Development and Evaluation of Fiber Optic Probe‐based Helium–Neon Low‐level Laser Therapy System for Tissue Regeneration—An In Vivo Experimental Study

01-Nov-2010 | Vijendra Prabhu; Satish B.S. Rao; Nageshwara B. Rao; Kiran B. Aithal; Pramod Kumar; Krishna K. Mahato, Photochemistry and Photobiology, 2010

Abstract We report the design and development of an optical fiber probe‐based Helium–Neon (He–Ne) low‐level laser therapy system for tissue regeneration. Full thickness excision wounds on Swiss albino mice of diameter 15 mm were exposed to various laser doses of 1, 2, 3, 4, 6, 8 and 10 J cm−2 ...


In Vitro Monitoring of Dissolution of an Immediate Release Tablet by Focused Beam Reflectance Measurement

04-Oct-2010 | Carrie A. Coutant; Michael J. Skibic; Greg D. Doddridge; Craig A. Kemp; David C. Sperry, Molecular Pharmaceutics, 2010

Changes in in vitro drug release profiles of oral dosage forms are commonly observed due to storage of drug product at elevated temperature and humidity. An example is presented of an immediate release drug product which underwent changes to both release profile and crystal form on storage at ...


E: Food Engineering and Physical Properties: FT‐NIR Spectroscopy for the Quality Characterization of Apricots (Prunus Armeniaca L.)

01-Sep-2010 | Berardinelli, Annachiara; Cevoli, Chiara; Silaghi, Florina Aurelia; Fabbri, Angelo; Ragni, Luigi; Giunchi, Alessandr ..., Journal of Food Science, 2010

Abstract:  The nondestructive assessment of apricot fruit quality (Bora cultivar) was carried out by means of FT‐NIR reflectance spectroscopy in the wavenumber range 12000 to 4000 cm−1. Samples were harvested at four different ripening stages and scanned by a fiber optical probe immediately after ...


A Fiber-Optic Fluorescence Microscope Using a Consumer-Grade Digital Camera for In Vivo Cellular Imaging

23-Jun-2010 | Dongsuk Shin et al., PLoS ONE, 2010

Background Early detection is an essential component of cancer management. Unfortunately, visual examination can often be unreliable, and many settings lack the financial capital and infrastructure to operate PET, CT, and MRI systems. Moreover, the infrastructure and expense associated with ...
