Bio-chip technology in Packaging Applications

Colonies have radioactive signal. Because the integrity of the original flat-panel contains all the colonies, so you can identify the required colony, and retained for further study. 3.2 Detection of specific protein in food packaging, packaging technology, packaging technology for the food protein ingredients will have different degrees. The variety of proteins out of food 'China Packaging 2003 / 6 into and content will determine the quality of wind ignorant of packaged goods. In the development of new products, need to detect certain proteins. One-time use of bio-chip can detect a variety of proteins. Microarray biochip technology uses antibodies and antigens, receptor and ligand interaction, a specific protein structure, function and modification of various aspects of research and development for the proteome provides a powerful tool. Microplate microarray technology is the technology to further miniaturization. Recently, Harvard University researchers have developed a compound micro-array chip. Mainly with the specific protein for screening specific - Pi binding compounds. They will slide surface chemical treatment, to produce derivatives of the active group, and then the compounds dissolved in organic solvents used in the robot point of the treated glass surface,[link widoczny dla zalogowanych], glass surface of the active compounds with reactive groups were fixed on the glass surface,[link widoczny dla zalogowanych], such compounds will be arranged into different micro-array, fixed on the glass surface, made of compounds microarray. 3.3 Packaging toxicological analysis and detection of many different packaging materials there is a certain degree of toxicity, especially in packaging materials and packaging components between the interdiffusion. Some toxic components, such as heavy metals, in the commodity storage period, will enter in the packaging. Therefore, packaging and products for toxicity evaluation, the process of packaging technology of a very important aspect. Toxicological studies now use more mice as a model, through animal experiments to determine the packaging materials and packaging of the potential toxicity. These methods take a few years, cost a lot. DNA microarray technology can be packaged with the gene expression characteristics of toxicity linked. Analysis of gene expression can be determined by the toxicity of packaging. DNA chips can be used simultaneously in an experiment on the expression of thousands of genes were analyzed for the study of molecular packing materials or heavy metals in the role of biological systems to provide new clues. The technology can be single or multiple hazardous substances analysis to determine the chemical conditions in the low-dose toxicity, analysis, inference of toxic substances on the toxicity of different biological comparability. If the different types of toxic substances if the corresponding characteristic gene expression patterns. Then, by comparing the control samples and gene expression profiles of toxic substances can be of various toxic substances are classified by this basis to further establish the appropriate biological model system, changes in gene expression can be passed to reflect the toxic human toxicity. At the same time. Bio-chip packaging can also be detected in the content of heavy metals and their compounds, to study the packing and packaging of micro reaction between. 4 Conclusion The bio-chip technology is a comprehensive high-tech, involving biological, chemical, medicine,[link widoczny dla zalogowanych], physics,[link widoczny dla zalogowanych], materials,[link widoczny dla zalogowanych], microelectronics, bioinformatics, precision instruments and other fields, is a highly interdisciplinary field of study. Although the bio-chip research so far has seen significant development, but some related technologies restricted its further development. For example, with the improvement of chip integration, the use of volume reduction reaction, which produces more and more weak signal, and thus, the requirement of high precision detector is imminent. In addition, the micro-processing technology, chip packaging and preservation is in the bio-chip research and development should focus on. In the bio-chip technology research and application development process, there are many unknown areas that require you to work on. However, with the technology, packaging technology is bound to open up a broad prospect. References 1. Jin even the group reviewed. Lijun Wen revision. Gene chip technology and microbiology.
