    Probes for formaldehyde (FA) including a homoallylamine trigger group attached to a detectable moiety are provided. Aspects of the probes include luminogenic or fluorogenic probes, such as a probe including a quencher in energy-receiving proximity to a fluroophore. Also provided are methods of using the probes for sensitive and bioorthogonal detection of FA in a sample. Aspects of the methods include selectively reacting the probe with the formaldehyde in the sample to a release (e.g., via a 2-aza- Cope rearrangement) a reporter group comprising a detectable moiety. Aspects of the methods detecting formaldehyde in a cell, tissue, organ or fluid in a subject. Also provided are compositions and kits including the subject probes that find use in practicing various embodiments of the subject methods.

    dyestuffs. Herein, we present the synthesis of a coumarin that can serve as a key starting material in the design and synthesis of bioorthogonally applicable fluorogenic dyes. The synthesis of 7‐azido‐3‐formylcoumarin started from 7‐diallylaminocoumarin. This allyl protected aminocoumarin is otherwise hard to obtain by conventional methods but was conveniently accessed in good yields by a sequential,

    Methods for detecting biomarkers of inflammation, infection, and/or bacterial activity in dairy production, which indicate issues with the milk itself or issues related to the health of the cow. The methods generally comprise contacting a milk sample with a nanoplatform assembly to create an assay solution, and detecting spectral changes in the assay solution that are triggered by enzymatic activity (when present) in the sample. The nanoplatform assembly comprises a first particle, a second particle, and a linkage therebetween, wherein the linkage comprises a protease consensus sequence (the sequence of amino acids cleaved by the protease), or an ester linkage (cleaved by a protease or lipase). A plurality of second particles can also be linked to the first particle. Test strips are also described, which undergo a visual color change in the presence of the target enzyme in the milk sample.

    A nanoplatform assembly for detection of arginase, indoleamine 2,3-dioxygenase 1, and/or tryptophan 2,3-dioxygenase. The nanoplatform comprises an oligopeptide, which is used as a linker between two particles. More preferably, the linker is comprised of an oligopeptide containing a substrate for the target enzyme, where the substrate is chemically or physically modified by the target enzyme (but not cleaved). A central particle with a plurality of oligopeptide-tethered detectable particles and a plurality of directly attached detectable particles is described. Posttranslational modification of the oligopeptide leads to changes in the detectable signals from the first and/or second particles in the nanoplatform, which can be correlated to enzyme activity and concentration.
