Abstract: An electrochemical detector includes: a solution chamber and a substance selection structure separating the chamber into individual compartments, wherein the solution chamber is arranged to retain and separate solutions in each of the individual compartments; and a pair of electrodes each connecting the respective individual compartment, wherein the pair of electrodes is arranged to form a conductive path across the electrodes when in contact with the solutions retained in the solution chamber. The substance selection structure is arranged to interact with a target substance in the solution so as to alter an electrical characteristic of the conductive path defined by the pair of electrodes, the solution retained in the individual compartments in the solution chamber and the substance selection structure.

Abstract: A method of inhibiting growth of a bacterium including steps of: a) delivering a polynucleotide including a sequence of SEQ ID NO: 1 or a homologue thereof to the bacterium, and b) contacting the bacterium with an effective amount of an antibiotic; wherein the bacterium is Pseudomonas aeruginosa. A method of treating a subject suffering from an infection caused by a bacterium which is Pseudomonas aeruginosa and the method including steps of: i) delivering said polynucleotide to a tissue infected by the bacterium or a bacterial cell in the subject; and ii) administering an effective amount of an antibiotic to the subject. A composition and a recombinant plasmid containing said polynucleotide.
