BIOLOGICAL DETECTION SYSTEM AND METHOD

摘要

The present disclosure provides a biological detection system and method. One detection system may include a genetically engineered phage that expresses a surface molecule able to bind a target molecule; a bacterium susceptible to infection by the phage; and a detection component able to determine whether the bacterium has been infected by the phage. Infection of a bacterium by a phage may be indicative of phage binding to the target molecule. One method may include placing a sample suspected of containing the target molecule with a binder; adding a genetically engineered phage having reporter genetic material and able to bind the target molecule; washing away unbound phage; releasing phage bound to the target molecule; infecting a bacterium with the released phage; and detecting the presence of any reporter genetic material in the bacterium. Reporter material in the bacterium may correlate with target molecule in the sample.
