| 摘要 |
Apparatus and methods are provided for improving sensitivity, throughput, and efficiency of multi-analyte analytical testing. Specifically, an improved Electrochemiluminescence (ECL) analytical apparatus is provided for analytical chemistry, diagnostics, and environmental applications. The ECL apparatus comprises a 96 or more-well plate, where a microarray of working electrodes is placed in each well for high throughput and multi-analyte testing. The microarray of working electrodes connects with a counter electrode forming a two-electrode electrochemical system. Each well is electrically addressable, thereby controlling ECL reactions in flexible modes. The ECL apparatus further comprises a detector of ECL signals, and the detector employs a CCD-chip assembling matrix. Also provided are methods for high-throughput multi-analyte testing. The methods according to this disclosure are applied in various embodiments to test a broad range of analytes, including chemical compounds, proteins, peptides, DNAs, RNAs, antigens, antibodies, pathogens, contaminants, and derivatives thereof.
