Summary: Rapid and low-cost molecular analysis is crucial for early and specific diagnostics. Automated molecular diagnostic devices, such as sample-to-answer microfluidic devices, promise a complete molecular diagnosis system. The extraction process in such devices is laborious but important for sensitive and specific detection. Thus, researching automated or semiautomated extraction methodologies is beneficial for improving extraction procedures.

Summary: This study presents a multi-amplification strategy based on paper-spray mass spectrometry for the analysis of miRNAs in blood. A toehold-mediated DNA-strand-displacement reaction is used to amplify the signal chain and ensure specificity. The paper spray method efficiently filters out interfering substances and enhances detection sensitivity.

Summary: Evolutionary biological processes lead to changes in heritable traits, where the responsible genetic information in DNA is altered, selected, and inherited through the mutation of the base sequence. Evolutionary changes at the molecular level of small organic molecules are unknown but represent an important prerequisite for the emergence of life, where catalysts can exhibit different selectivity during formation.

Summary: Majority of studies show that mNGS has similar sensitivity to specific PCR assays and can identify more potential pathogens than conventional methods. Concerns remain about contamination and detection of nonclinically significant organisms, highlighting the importance of careful interpretation of pathogenicity and potential association with clinical syndromes. Further research is needed to evaluate the improvement in clinical outcomes and cost-effectiveness of mNGS testing.

Summary: This review examines a wide range of methods for detecting DNA and RNA at single-digit attomolar concentrations without the need for nucleic acid amplification. These methods correspond to the clinically desirable detection range for pathogen-specific nucleic acid and are close to the detection limits of commercially available nucleic acid amplification tests based on PCR. With the ongoing pandemic, the demand for faster, more cost-effective, yet highly accurate tests has become increasingly evident.

Summary: This review systematically summarized the origins, development, basic mechanism, and limits of reductant-enhanced iron-based peroxide activation processes. It was found that the use of reductants could accelerate the reduction of Fe3+ and quench the production of reactive species, with the trade-off determined by intrinsic chemical properties and experimental conditions. Additionally, practical application potential of different reductants based on toxicity, costs, and self-transformation products was evaluated, and new enhancement strategies were proposed for future research needs.
