食品中重金属砷检测的研究进展
Advances on arsenic detection in food
摘要
Abstract
Food safety is a major issue in 21st century in food industry because it is related to people's life quality and health safety.In recent years,arsenic in food contamination incidents happened frequently,which caused severely damages to people's health.Although traditional techniques have high selectivity and sensitivity,they still have some shortcomings,such as large bulky test equipment,complicated pre-treatment and high cost.With the progress of nucleic acids research,detection method with aptamers are widely used.Aptamer is a single-stranded DNA or RNA sequence,which can identify a specific target molecule.Aptamer is screened through in vitro,which has a stable secondary structure,high affinity and easy of chemical modification and so on.After 20 years of development,aptamer has developed into a new recognition molecules,which attracted wide attention of multidisciplinary researchers.At present,aptamer has become an important heavy metal detecting tool,while few studies have applied it into arsenic detection.In this paper,the advantages and disadvantages of the traditional testing methods and standards testing methods are evaluated,and application of aptamers in food safety analysis are summarized and prospected.关键词
