Pathogen biosensors for food safety and public healthcare based on specific biological probes biopanned by phage display: A critical review.

Pathogens are one of the primary threats to the environment, food safety and public healthcare. Rapid, selective and sensitive detection methods or biosensors are crucial in are crucial in effectively evaluating pathogen-induced emergency. Phage display is powerful in rapidly screening specific biological probes with high affinity.

Sensitive amperometric immunosensor for pathogen antigen based on MoS@AuNPs assembling dual-peptide as bioprobes with significant dual signal amplification.

It is crucial to timely and accurately identify the causative virus for early treatment and urgent prevention. Viral antigen detection can identify those people who are most likely at risk of spreading the disease, but most based on antibodies with limited stability and sensitivity. Peptides offer several advantages over antibodies, such as low cost, smaller size and good stability.

Sensitive Dual-Signal ELISA Based on Specific Phage-Displayed Double Peptide Probes with Internal Filtering Effect to Assay Monkeypox Virus Antigen.

The global spread of monkeypox has become a worldwide public healthcare issue. Therefore, there is an urgent need for accurate and sensitive detection methods to effectively control its spreading. Herein, we screened by phage display two peptides M4 (sequence: DPCGERICSIAL) and M6 (sequence: SCSSFLCSLKVG) with good affinity and specificity to monkeypox virus (MPXV) B21R protein.

Effect of cerium on the production of reactive oxygen species in the root of Arabidopsis thaliana: An in vitro study.

In the current study, the effect of trivalent cerium (Ce ) on the production of reactive oxygen species (ROS) was investigated in the root of Arabidopsis thaliana by an in vitro study. The roots of A. thaliana were exposed with 0, 1, and 5 μmol/L Ce for 12 h in vitro.
