The field of fluorescent nanodiamonds (FNDs) has advanced greatly over the past few years. Though historically limited primarily to red fluorescence, the wavelengths available for nanodiamonds have increased due to continuous technical advancement. This Review summarizes the strides made in the synthesis, functionalization, and application of FNDs to bioimaging. Highlights range from super-resolution microscopy, through cellular and whole animal imaging, up to constantly emerging fields including sensing and hyperpolarized magnetic resonance imaging.

Ethnopharmacological Relevance: Vulvovaginal candidiasis (VVC) is a relatively common fungal infectious disease in the female reproductive tract. The pathogenesis of VVC not only involves Candida albicans (C. albicans) infection, but also the improper immune response of the vaginal mucosal immune system to the fungus.

detection suffers from slow analysis time and high costs, along with the need for specificity. While state-of-the-art electrochemical biosensors are cost-efficient and easy to implement, their sensitivity and analysis time still require improvement. In this work, we present a paper-based electrochemical biosensor utilizing magnetic core-shell FeO@CdSe/ZnS quantum dots (MQDs) to achieve fast detection, low cost, and high sensitivity.

Nanomaterials have attracted significant attention as signal reporters for immunoassays. They can directly generate detectable signals or release a large number of signaling elements for readout. Among various nanolabels, nanomaterials composed of multiple signaling molecules have shown great potential in immunoassays.

Activation of cannabinoid CB receptors (CBR) by agonists induces analgesia but also induces cognitive impairment through the heteromer formed between CBR and the serotonin 5HT receptor (5HTR). This side effect poses a serious drawback in the therapeutic use of cannabis for pain alleviation. Peptides designed from the transmembrane helices of CBR, which are predicted to bind 5HTR and alter the stability of the CBR-5HTR heteromer, have been shown to avert CBR agonist-induced cognitive impairment while preserving analgesia.

The spontaneous adsorption of proteins onto nanoparticles, known as the protein corona, provides a unique perspective for designing protein-sensing biosensors. This study proposes a tailored protein corona method mediated by Tween-20 and develops a reverse-capture approach for protein quantification assays. The protein-coated microplate captures titanium dioxide nanosheets (TiO-NS) in a phosphate buffer containing Tween-20 and generates fluorescence signals via the photocatalytic reduction of resazurin to resorufin, thereby indicating the amount of protein.
