TL;DR: A novel nanoprobe for detection and imaging of ascorbic acid in living cells and in vivo based on the specific reaction of cobalt oxyhydroxide and AA is reported, which shows high selectivity and an instantaneous response.
Abstract: The development of a specific reaction of nanomaterials and reactive species is of fundamental importance for the determination of biomolecules. Here we report a novel nanoprobe for detection and imaging of ascorbic acid (AA) in living cells and in vivo based on the specific reaction of cobalt oxyhydroxide (CoOOH) and AA. Persistent luminescence nanoparticles (PLNPs) were used as the luminescence unit, and CoOOH nanoflakes served as the quencher. When CoOOH was modified on the surface of the PLNPs, the luminescence of the PLNPs was efficiently quenched by the CoOOH. In the presence of AA, CoOOH was reduced to Co(2+) and the luminescence of PLNPs was restored. The nanoprobe showed high selectivity and an instantaneous response. The luminescence property permits detection and imaging without external excitation, which could effectively avoid background noise and scattering of light from biological matrixes produced by in situ excitation. The current strategy provides an effective platform for monitoring and imaging reactive species in living cells and in vivo.

Abstract: In this Feature, electrochemiluminescent (ECL) and photoelectrochemical (PEC) properties and mechanisms of semiconductor quantum dots (QDs) are reviewed, with emphasis on their specific fundamentals and concise comparison on their similarities and differences. With recent illustrative examples of bioanalytical applications, the main signaling strategies for QDs-based ECL and PEC bioanalysis are then highlighted. The future prospects in this field are also discussed.

TL;DR: By dealloying predesigned Al-based precursor alloys, it is possible to controllably incorporate Ir with another four metal elements into one single nanostructured phase with merely ≈20 at% Ir, and a record-high OER activity is found for a quinary AlNiCoIrMo np-HEA.
Abstract: Ir-based binary and ternary alloys are effective catalysts for the electrochemical oxygen evolution reaction (OER) in acidic solutions. Nevertheless, decreasing the Ir content to less than 50 at% while maintaining or even enhancing the overall electrocatalytic activity and durability remains a grand challenge. Herein, by dealloying predesigned Al-based precursor alloys, it is possible to controllably incorporate Ir with another four metal elements into one single nanostructured phase with merely ≈20 at% Ir. The obtained nanoporous quinary alloys, i.e., nanoporous high-entropy alloys (np-HEAs) provide infinite possibilities for tuning alloy's electronic properties and maximizing catalytic activities owing to the endless element combinations. Particularly, a record-high OER activity is found for a quinary AlNiCoIrMo np-HEA. Forming HEAs also greatly enhances the structural and catalytic durability regardless of the alloy compositions. With the advantages of low Ir loading and high activity, these np-HEA catalysts are very promising and suitable for activity tailoring/maximization.

TL;DR: A four-color nanoprobe composed of gold nanoparticles functionalized with a dense shell of molecular beacons, which can identify multiple intracellular mRNA transcripts, shows rapid response, high specificity, nuclease stability, and good biocompatibility.
Abstract: Simultaneous detection and imaging of multiple intracellular biomarkers hold great promise for early cancer detection. Here, we introduce a four-color nanoprobe that can simultaneously detect and image four types of mRNAs in living cells. The nanoprobe composed of gold nanoparticles functionalized with a dense shell of molecular beacons, which can identify multiple intracellular mRNA transcripts. It shows rapid response, high specificity, nuclease stability, and good biocompatibility. Intracellular experiments indicate that the nanoprobe could effectively distinguish cancer cells from their normal cells, even some mRNAs are overexpressed in normal cells. Moreover, it can identify the changes of the expression levels of mRNA in living cells. The current strategy could provide more-accurate information for early cancer detection and availably avoid false positive results.
