Molecular detection is a field of research that focuses on the identification and measurement of specific molecules within a sample using various molecular techniques. These techniques can include polymerase chain reaction (PCR), DNA sequencing, hybridization assays, and other methods that allow for the detection of specific nucleic acids, proteins, or other molecules of interest. Molecular detection is commonly used in various scientific disciplines, including microbiology, genetics, and biotechnology, and is important for applications such as disease diagnosis, forensic analysis, environmental monitoring, and food safety testing.
