Abstract:
... Monitoring the presence of genetically modified organisms (GMOs) in a variety of food is important to many countries, as the law requires that the approved GMOs should be labeled as such. In addition, before genetically modified crops are used to obtain feed for the livestock, tests must be carried out to screen unapproved genetically modified varieties. Therefore, it is necessary to be able to de ...

Abstract:
... Textiles, especially apparel, play an essential role in our daily life. Given that nearly everybody is in contact with clothes and other textiles 24 h a day, they have to be safe. Today’s manufacturing processes depend on the use of many different chemicals, including dyes. An ideal dye would stay within the fabric during use. However, most textile dyes are prone to leaching and wear-off. Ideally, ...
