Abstract
Highly sensitive and reliable detection of multiple myeloma remains a major challenge in liquid biopsy. Herein, for the first time, quantum dot-molecular beacon (QD-MB) functionalized MoS2 (QD-MB @MoS2) fluorescent probes were designed for the dual detection of multiple myeloma (MM)-related miRNA-155 and miRNA-150. The results indicate that the two probes can effectively detect miRNA-155 and miRNA-150 simultaneously with satisfactory recovery rates, and the limit of detections (LODs) of miRNA-155 and miRNA-150 in human serum are low to 7.19 fM and 5.84 fM, respectively. These results indicate that our method is the most sensitive detection so far reported and that the designed fluorescent probes with signal amplification strategies can achieve highly sensitive detection of MM-related miRNAs for MM diagnosis. Novel quantum dot-molecular beacon functionalized MoS2 (QD-MB@MoS2) fluorescent probes were designed and fabricated. The dual detection of miRNA-155 and miRNA-150 with high sensitivity, low detection limit and high recovery was realized. The fluorescence probes have a great influence on the fluorescence quenching efficiency and the sensitivity. The new MB@MoS2 fluorescent probe and dual detection strategy provide a valuable tool for the detection of miRNA.

Abstract
Dengue fever is a classic mosquito viral disease. Dengue virus non-structural protein-1 as a membrane-associated homologous dimer anchored to the surface of infected cells and also secreted into the blood. The nonstructural protein-1 levels are related to disease severity, and the presence of nonstructural protein-1 secreted from cells to the serum of people infected with the dengue virus is an early marker of infection. Paired antibodies are key in the establishment of rapid detection technology. In this study, the prepared recombinant nonstructural protein-1 protein of dengue virus serotype 3 was purified by the prokaryotic expression, and prepared monoclonal antibodies by cell fusion. A method for paired antibody screening was established based on the N-hydroxy succinimide-nanobeads and the prepared monoclonal antibodies. A simple and rapid point-of-care system integrating the paired antibodies and lateral flow assay was established to verify the screened antibody pairs. The results confirmed that the antibody pair screening method based on N-hydroxy succinimide-nanobeads is feasible.
