Sol-gel processing is an attractive method for large-scale surface coating due to its facile and inexpensive preparation, even with the inclusion of precision nanotopographies. These are desirable traits for metal orthopaedic prostheses where ceramic coatings are known to be osteoinductive and the effects may be amplified through nanotexturing. However there are a few concerns associated with t...

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis following tryptic digestion of polyacrylamide gel pieces is a common technique used to identify proteins. This approach is rapid, sensitive, and user friendly, and is becoming widely available to scientists in a variety of biological fields. Here we introduce a simple and effective strategy called "mass proces...

We have developed a powerful image processing system DNAinsight, which performs automated detection of several thousands of spots found on autoradiogram images obtained with 2-D gel electrophoresis of genomic DNA. Algorithms and parameters for detecting spot locations and intensities are carefully chosen so as to enable reliable and rapid processing of 2-D gel electrophoretograms based on the R...

Time-table problem is a classical NP-complete problem. Algorithm of DNA computing for timetable problem was obtained with introducing the technology of Acrydite gel separation. Each class period viewed as a graph vertex was mapped into DNA molecules chain. With the probe coding, the gel column was constructed to arrange the order of DNA chain through biological reaction. The problem was solved ...

Two-dimensional Electrophoresis Gel Images Scan (2dEGIS) implements a mix of computational methods for processing two-dimensional electrophoresis gel images. For advancing the analysis in case-control sample studies, a multi-component decompositionapproximation approach is presented, based on: (1) A global scan aimed to detect discriminative patterns with just a few components; (2) A more local...

We report on the fabrication and characterization of thick UV-patternable hybrid sol-gel films by spin coating using a modified sol-gel process. Thick coating of 25 microns with crack-free surface can be produced by one spin coating step. Thick layers of more than 100 μm can be obtained with a multi-coating process. Characterization using different techniques including optical microscope and at...

A novel density barrier material, Phase Lock Gel, has been formulated and optimized for use in enhancing the separation between aqueous and organic phases during organic extraction/ centrifugation of nucleic acids. Phase Lock Gel is inert, stable to heating, compatible with most enzymatic reactions of nucleic acids without sacrificing subsequent downstream applications, and can be easily and co...
