Method and apparatus for detecting and quantifying bacterial spores on a surface
A method and an apparatus for detecting and quantifying bacterial spores on a surface. In accordance with the method: a matrix including lanthanide ions is provided on the surface containing the bacterial spores; functionalized aromatic molecules are released from the bacterial spores on the surface; a complex of the lanthanide ion and the aromatic molecule is formed on the surface; the complex of the lanthanide ion and the aromatic molecule is excited to generate a characteristic luminescence of the complex on the surface; and the bacterial spores exhibiting the luminescence of the complex on the surface are detected and quantified.
1. A method for detecting and quantifying individual bacterial spores, the method comprising
imaging the individual bacterial spores on a matrix comprising a lanthanide ion,
wherein the imaging is performed following release of aromatic molecules from the individual bacterial spores and subsequent excitement of a complex formed by the lanthanide ion and the aromatic molecules to generate a luminescence; and
wherein the imaged individual bacterial spores exhibit the luminescence of the complex on the matrix.
2. The method according to claim 1 , wherein the matrix further comprises at least one polymer.
3. The method according to claim 2 , wherein the at least one polymer is an adhesive polymer.
4. The method according to claim 3 , wherein the at least one adhesive polymer is transparent down to about 250 nm, thereby providing a transparent test surface.
