Microbial Identification and Quantitation Using MS Cleavable Tags
20230236189 · 2023-07-27 ·

Systems and methods are provided for microbial identification using cleavable tags. Control information is sent to a mass spectrometer to fragment one or more nucleic acid primers labeled with a first tag and monitor for an intensity of the first tag in a mass spectrometry (MS) method. An ion source provides a beam of ions from a polymerase chain reaction amplified sample that includes one or more nucleic acid primers labeled with the first tag. The first tag binds to one or more nucleic acid primers of a known microbe and is cleaved from the nucleic acid primers during the MS method. The mass spectrometer receives the beam of ions and is adapted to perform the MS method on the beam of ions. If the intensity of the first tag received from the mass spectrometer exceeds a threshold value, the known microbe is identified in the sample.

The present invention also refers to device for analysing a liquid sample as to the presence, identity and properties of microbes, wherein the device comprises as a first unit (i) a chip comprising a filtering unit and an antibiotics exposure unit capable of determining the susceptibility of microbes to an antibiotic; as a second unit (ii) a Raman spectroscopy system; and as a third unit (iii) an evaluation module which is coupled to the Raman spectroscopy system.

BACTERIAL BETA-LACTAMASE RESPONSIVE HYDROGELS
20230029034 · 2023-01-26 ·

The invention provides a “host-guest” supramolecular hydrogel. The hydrogel contains an AAm/NVP interpenetrating polymer network (IPN) with supramolecular cross-linkers assembled from β-lactam/adamantane-containing guest molecule with host polymeric cyclodextrin (PCD). An advantage of this hydrogel is that because of the molecular association of polymeric cyclodextrin and adamantane, the supramolecular hydrogels self-heal without any external stimuli after the hydrogels are severed. The invention also provides methods of making the hydrogel, methods of making the synthesis intermediates, and methods of diagnosis or treatment of β-lactamase-containing bacteria.
