Abstract
A colorimetric and/or fluorescent detector, which comprises a film of polydiacetylenes and lipids deposited on a substrate, wherein said film is coated with one or more layers, wherein at least one of said layers is capable of supporting the growth of microorganisms. Also provided are processes for preparing the novel colorimetric and/or fluorescent detector and uses thereof in the detection of bacteria.
Claims14
1) A colorimetric and/or fluorescent detector, which comprises a film of polydiacetyelenes and lipids deposited on a substrate, wherein said film is coated with one or more layers, wherein at least one of said layers is capable of supporting the growth of microorganisms.
7) A process for preparing colorimetric and/or fluorescent detector, which comprises depositing a film of diacetylenes and lipids on a substrate, polymerizing the diacetylene monomers and coating said film with one or more coating layers, wherein at least one of said layers is made of a material which is capable of supporting the growth of microorganism.
8) A process for preparing colorimetric and/or fluorescent detector, which comprises depositing a film of diacetylenes and lipids on a substrate, coating said film with one or more coating layers, wherein at least one of said layers is made of a material which is capable of supporting the growth of microorganism, and polymerizing the diacetylene monomers.
9) A method for detecting the presence of an analyte in a sample, comprising contacting the sample to be tested with a film of polydiacetyelenes and lipids deposited on a substrate, wherein said film is coated with one or more layers, wherein at least one of said layers is capable of supporting the growth of microorganisms, and following a suitable incubation period, either observing the color of said coated film or the fluorescence emission thereof, wherein a change in said color or a characteristic fluorescence emission indicate the presence of said analyte in the tested sample.
