Abstract
Lateral flow assay (LFA) type of biosensors have been popular due to cost-effectiveness and easy-interpretation for instant results, most common examples of applications being pregnancy tests, food safety or medical diagnostics. There are several examples of reports with high sensitivity, including pre-concentration of the sample by magnetic pull-down. However, sensitivity and direct detection designs with aptamers has been a limiting factor for developing aptamers-based LFA assays. In this study, we report a lateral flow design based on aptamer-gated silica nanoparticles to develop high sensitivity and direct bacterial assay by shifting aptamers-target interaction to conjugation pad. Aptamer-gated silica nanoparticles-based biosensors were reported for their high sensitivity, specificity and label-free detection for small molecules and whole cells. This label-free strategy for LFA can determine L. monocytogenes in minced chicken matrix at less than 5 min with a limit of detection (LOD) of 53 cells in one mL samples.

Abstract
Infectious diseases are transmissible or communicable illnesses and can spread quickly in some areas and become epidemics. It is critical to quickly diagnose initial infections and prevent further spread through in vitro diagnosis. However, current detection strategies have exhibited a lack of balance with regard to accuracy, time consumption, and portability until recently (e.g. serology, culturing, molecular tests, etc.). Alternatively, many studies have focused on point-of-care testing (POCT), which combines simple, rapid, and exact on-site diagnostic platforms. Moreover, multiplex detectability is necessary for emergency treatment depending on the stage of the disease or interactional infections. The lateral flow assay (LFA) is the most popular diagnostic tool that meets the required standards for colorimetric assays. Here, we review lateral flow assays based on the immune reactions for the simultaneous diagnosis of infectious diseases as the POC test. The assays employed various forms and approaches in terms of the multiplexing level system for improving the sensitivity and specificity. We briefly describe the state-of-the-art infection diagnostic methods and published performances that have been classified into three categories based on the application forms of the lateral flow immunoassay. Also, we discuss further uses of LFA and other technologies for more effective infectious disease POCT.

Abstract
Nanozyme-based chemical sensing is a rapidly emerging field of research. Herein, a simple colorimetric assay for the detection of hydrogen peroxide and glucose based on the peroxidase-like activity of V₂O₅ nanozymes has been established. In this assay, the effects of pH, substrate, nanozyme concentrations and buffer solution have been investigated. It was found that compared with 3,3',5,5'-tetramethylbenzidine (TMB), the enzyme substrate o-phenylenediamine (OPD) seriously interfered with the H₂O₂ detection. Under the optimal reaction conditions, the resulting sensor displayed a good response to H₂O₂ with a linear range of 1 to 500 μM, and a detection limit of 1 μM at a signal-to-noise ratio of 3. A linear correlation was established between absorbance intensity and concentration of glucose from 10 to 2000 μM, with a detection limit of 10 μM. The current work presents a simple, cheap, more convenient, sensitive, and easy handling colorimetric assay.
