Última Novel Techniques for Microspectroscopy and Chemical Imaging Analysis of Soybean Seeds and Embryos Nature Precedings I. C. Baianu; Tiefeng You; Doina M. Costescu. Novel methodologies are currently being evaluated for the Chemical Analysis of soybean seeds as well as developing mature soybean embryos by FT-IR/NIR Microspectroscopy. This is the first report of FT-NIR Chemical Images obtained with 1 micron resolution. NIR spectra of Proteins, Oil and DNA fibers are obtained for regions as small as 1μ^2^.

Ano: 2011 URL: http://precedings.nature.com/documents/6591/version/1 Soybean Composition Database from NIR, NMR and GC-MS Analyses- (v.3) Nature Precedings I. C. Baianu; Tiefeng You; Jun Guo; Doina M. Costescu; V. I. Prisecaru. This novel Soybean Composition Database from the AFC-NMR & NIR Spectroscopy Facility of the College of ACES at the University of Illinois at Urbana includes more than 12,000 NIR measurements on soybeans from the International Soybean Germplasm Collection, such as those received from Peking at the National Soybean Collection.
Excel files (.xls) of our novel spectroscopic data are currently available for all 80,000 + NIR and FT-NMR measurements; such data are made available from an ultra-fast and secure supercomputer server utilizing the current version of the Scientific-Linux OS-based software. 

A detailed account is also presented of our high-resolution nuclear magnetic resonance (HR-NMR) and...

Ano: 2011 URL: http://precedings.nature.com/documents/6201/version/3 NMR and Electron Microscopy Studies of Soybean Seeds, Soybean Proteins, and Oil for Improved Utilization in Foods and Feeds Nature Precedings Doina M. Costescu; I. C. Baianu. NMR, NIR and EM techniques are suitable methods of measuring protein and oil content in soybeans. After completion of a measurement with NMR or NIR, a soybean sample could be either replanted or consummated. NMR techniques involved in the present work are based on the response of nuclei, as nuclear spin flips, when set in a 7.05T magnetic field and excited with rf pulses of 300 MHz. NIR spectroscopy is based on outer electron molecular vibrations, when excited with radiation of frequency 1012 -4×1014Hz, and =2.5Om-750 nm. 
TEM and ESEM techniques are bulk and surface analysis techniques, respectively, working with electron beams of 15KV, and image resolution in the range of nm’s. ESEM is based on the...

Ano: 2011 URL: http://precedings.nature.com/documents/6192/version/1 Single Cancer Cell Detection by Near Infrared Microspectroscopy, Infrared Chemical Imaging and Fluorescence Microspectroscopy Nature Precedings I. C. Baianu; Schuyler S. Korban; Doina M. Costescu. Novel techniques are currently being developed and established for the accurate chemical analysis and detection of single cancer cells, single embryos and single seeds by Fourier Transform Near Infrared (FT-NIR) Microspectroscopy, Fourier Transform Infrared (FT-IR), Fluorescence and High-Resolution NMR (HR-NMR). The first FT-NIR chemical images of biological systems approaching 1micron resolution are here reported. 400 and 500 MHz, H-1 NMR analyses were carried out that allowed the selection of mutagenized embryos. Detailed chemical analyses are being demonstrated to be also possible by FT-NIR Chemical Imaging/ Microspectroscopy of single cancer cells. FT-NIR Microspectroscopy and Chemical Imaging are also shown to be potentially important in Functional...

Ano: 2011 URL: http://precedings.nature.com/documents/6207/version/1 NIR Calibrations for Soybean Seeds and Soy Food Composition Analysis: Total Carbohydrates, Oil, Proteins and Water Contents [v.2] Nature Precedings I. C. Baianu; Jun Guo; Randall L. Nelson; Tiefeng You; Doina M. Costescu. Conventional chemical analysis techniques are expensive, time consuming, and often destructive. The non-invasive Near Infrared (NIR) technology was introduced over the last decades for wide-scale, inexpensive chemical analysis of food and crop seed composition (see Williams and Norris, 1987; Wilcox and Cavins, 1995; Buning and Diller, 2000 for reviews of the NIR technique development stage prior to 1998, when Diode Arrays were introduced to NIR). NIR spectroscopic measurements obey Lambert and Beer’s law, and quantitative measurements can be successfully made with high speed and ease of operation. NIR has been used in a great variety of food applications. General applications of products analyzed come from all sectors of the food industry...
