Multi-use biosensors are disclosed that include enzymes coupled to nanobeads; the multi-use biosensors are used to detect analytes in fluidic biological samples, and the biosensors also maintain their enzyme activity after many uses. Multi-sensor arrays are disclosed that include multiple biosensors. Also disclosed are methods of producing and using these devices.

The present invention relates to a kit for the detection of urease and to a tool and a composition forming part of the kit. In particular, the present invention relates to a kit for the detection of urease which comprises a composition containing an indicator; a delivery tool arranged to deliver a tissue sample into contact with the composition; and urea carried on the delivery tool, whereby the urea is arranged to be delivered to the composition together with the tissue sample.

A method of treating breast cancer is described, in which a peptide having cancer selective translocation function-doxoribicin conjugate is administered. The conjugate includes doxorubicin chemically linked to the N-terminus or C-terminus of a VEGF-binding protein transduction domain (VPTD) peptide represented as SEQ ID NO: 1, wherein the VPTD peptide and doxorubicin are linked to each other by a disulfide bond, and wherein the VPTD peptide binds specifically to vascular endothelial growth factor (VEGF) in tumor cells or tumor tissues.

A diagnostic device 10 for screening for a target analyte in a sample is provided. The diagnostic device 10 comprises a substrate 12 and a hydrophobic material 20 disposed on the substrate. The hydrophobic material 20 is selected to be converted from the hydrophobic material 20 to a hydrophilic material 22 upon contact with a conversion component within or derived from a sample introduced to the device 10.
