Pertains to the design and applications of platinum (II) compounds supported by a bidentate and N-heterocyclic carbene ligands. The Pt (II) complexes exhibit strong emission intensity differences when contacted with matched and mismatched DNA. In addition, the Pt (II) complexes show a color tunable effect when exposed to mismatched compared to matched DNA, which color effect can be easily detected.

Provided herein are methods, compositions, and kits for determining a location of a target analyte in a biological sample that include the use of terminal deoxynucleotidyl transferase.

The present methods are exemplified by a process in which maternal blood containing fetal DNA is diluted to a nominal value of approximately 0.5 genome equivalent of DNA per reaction sample. Digital analysis is then be used to detect aneuploidy, such as the trisomy that causes Down Syndrome. Since aneuploidies do not present a mutational change in sequence, and are merely a change in the number of chromosomes, it has not been possible to detect them in a fetus without resorting to invasive techniques such as amniocentesis or chorionic villi sampling. Digital amplification allows the detection of aneuploidy using massively parallel amplification and detection methods, examining, e.g., 10,000 genome equivalents.
