Abstract
Molecular immobilization and recognition are two key events for the development of biosensors. The general ways for the immobilization and recognition of biomolecules include covalent coupling reactions and non-covalent interactions of antigen-antibody, aptamer-target, glycan-lectin, avidin-biotin and boronic acid-diol. Tetradentate nitrilotriacetic acid (NTA) is one of the most common commercial ligands for chelating metal ions. The NTA-metal complexes show high and specific affinity toward hexahistidine tags. Such metal complexes have been widely utilized in protein separation and immobilization for diagnostic applications since most of commercialized proteins have been integrated with hexahistidine tags by synthetic or recombinant techniques. This review focused on the development of biosensors with NTA-metal complexes as the binding units, mainly including surface plasmon resonance, electrochemistry, fluorescence, colorimetry, surface-enhanced Raman scattering spectroscopy, chemiluminescence and so on.

Abstract
We have developed a novel FRET-based assay to monitor protein kinase activity using quantum dots (QDs) and fluorophore-labeled substrate peptides. To develop a FRET-based protein kinase assay, it is important to consider the phosphate group recognition strategy and to ensure that the FRET pairs are close enough because the FRET efficiency is highly dependent on the distance between the FRET pairs. Here, we incorporated a phos-tag, which captures phosphate groups strongly and selectively, into a protein kinase assay to recognize phosphorylation. Our detection system was composed of phos-tag-modified QDs and Cy5-labeled substrate peptides. Because the phos-tags capture phosphate groups by forming dinuclear complexes, the Cy5-labeled substrate peptides are captured by the phos-tags on the QD surface upon protein kinase-mediated phosphorylation, which induces FRET from the QDs to Cy5 because of the approximation of Cy5 to the QDs. On the basis of the difference of this FRET efficiency, we successfully measured protein kinase A activity, which demonstrated the feasibility of our assay.

Abstract
In cell-signaling pathways, protein kinases are critical and ubiquitous regulators. Abnormal kinase activity leads to many major diseases; therefore, simple and efficient methods for detecting protein kinases are in high demand. This study proposed a simple, rapid fluorescence-based sensor for protein kinase activity analysis, using the zirconium-based metal organic framework UiO-66 as a highly efficient affinity probe. UiO-66 has a large specific surface area, good stability, and a large number of Zr defect sites, which can efficiently identify phosphorylation sites. UiO-66 is an ideal nanoreactor that can efficiently enrich phosphorylated peptides. Under optimal experimental conditions, the increased fluorescence intensity was directly proportional to the protein kinase activity. The lower limit of detection was 0.00005 U·μL-1. The assay could also be used for the screening of protein kinase inhibitors, could determine the activity of other kinds of kinases, and was universally applicable. This method was used for protein kinase activity detection in drug-stimulated MCF-7 cell lysates and demonstrated its potential applicability in kinase-related research.

Abstract
In this work, a novel and sensitive photoelectrochemical (PEC) strategy was designed for protein kinase A (PKA) detection, comprising carbon microsphere (CMS) modified ITO electrode, TiO2 as the phosphate group recognition material and graphite-carbon nitride (g-C3N4) as photoactive material. For the first time, gold nanoparticle decorated zeolitic imidazolate frameworks (Au-ZIF-8) was employed to fabricate biosensor for PKA activity assay with the function of substrate peptide immobilization and signal amplification. Firstly, substrate peptides were assembled on the Au-ZIF-8/CMS/ITO surface through the covalent bonding between the gold nanoparticles (AuNPs) and sulfydryl groups of the peptides. Then, in the presence of ATP, phosphorylation of the substrate peptide was achieved under PKA catalysis. Finally, TiO2-g-C3N4 composites were further modified on the electrode surface based on bonding between TiO2 and phosphate groups created via phosphorylation of the peptide (yielding TiO2-g-C3N4/P-peptide/Au-ZIF-8/CMS/ITO), which is different with our previous work by directly immobilizing g-C3N4 composite on electrode surface. The developed method showed a wide linear range from 0.05-50 U mL-1. The detection limit was 0.02 U mL-1 (S/N = 3). The constructed biosensor exhibited high detection specificity for PKA. In addition, the wide applicability of this biosensor was demonstrated by evaluating the inhibition ability of ellagic acid towards PKA.

Abstract
Phosphorylation mediated by protein kinases plays a pivotal role in metabolic and cell-signaling processes, and the dysfunction of protein kinases such as protein kinase A (PKA) may induce several human diseases. Therefore, it is of great significance to develop a facile and effective method for PKA activity assay and high-throughput screening of inhibitors. Herein, we develop a new fluorescent off-on method for PKA assay based on the assembly of anionic polyuridylic acid (polyU) and cationic fluorescent peptide. The phosphorylation of the peptide disrupts its electrostatic binding with polyU, suppresses the concentration quenching effect of polyU, and thus causes fluorescence recovery. The recovered fluorescence intensity at 585 nm is directly proportional to the PKA activity in the range of 0.1-3.2 U/mL with a detection limit of 0.05 U/mL. Using our method, the PKA activity in HeLa cell lysate is determined to be 58.2 ± 5.1 U/mg protein. The method has also been employed to evaluate the inhibitory effect of PKA inhibitors with satisfactory results and may be expected to be a promising candidate for facile and cost-effective assay of kinase activity and high-throughput inhibitor screening.
