within living cells, with the highly efficient labeling of subcellular components and the activation of prodrugs. In vivo applications, however, have been scarce, with a need for the specific cellular targeting of the active transition metals. Here, we show the design and application of cancer‐targeting palladium catalysts, with their specific uptake in brain cancer (glioblastoma) cells, while maintaining
cell-permeable peptide probe with a ratiometricfluorescence response specifically toward caspase-3, a key enzyme for the execution of apoptosis. This probe Ac-Tat-DEVD-CV consisted of a caspase-3 recognition sequence Asp-Glu-Val-Asp (DEVD), a cell-penetrating peptide Tat (RKKRRORRR), and a long wavelength fluorophore, cresyl violet (CV). Upon selective hydrolyzation by caspase-3, the probe released CV and

Novel fluorogenic compounds designed such that upon a chemical event, compounds capable of emitting NIR light are generated, are disclosed. The compounds comprise two or more acceptor-containing moieties and a cleavable donor-containing moiety, being in complete pi-electrons conjugation and being such that no delocalization of pi-electrons is enabled. Also disclosed are fluorescent compounds generated upon subjecting the fluorogenic compounds to a chemical event (e.g., deprotonation). Also disclosed are uses of the fluorogenic compounds as NIR probed with a Turn-ON mechanism in monitoring presence and/or level of various analytes.

A simple method for measuring allergens is disclosed, by which the amount of environmental allergens can be measured simply without using an anti-allergen antibody. In the method for measuring an environmental biological allergen(s), a solution containing a substrate of a protease which the allergen(s) has(have) is brought into contact with a test sample collected by using an adhesive sheet, which substrate gives a visible color change as a result of an enzyme reaction; and measuring the protease activity in the test sample using the color change of the substrate solution as an index, thereby measuring the biological allergen(s).
