This paper develops a label-free diagnostic platform for HIV detection with smartphone integration, achieving attomolar sensitivity without sample pre-treatment.

This paper develops a portable smartphone-integrated RPA-CRISPR-Cas12a system for early detection of potato late blight using microneedle sampling, achieving high sensitivity and field usability.

The paper develops a polyvinyl alcohol microneedle system for precise delivery of small molecules to plants, showing higher efficiency and reduced chemical use compared to traditional methods.

This paper introduces a nondestructive DNA extraction method using microneedles for crop seeds, enabling rapid genotyping and maintaining seed viability for further use.

This paper develops a paper-based colorimetric sensor array with needles for rapid, minimally invasive VOC detection in vegetables, enabling quick quality assessment.

The paper develops a ratiometric CRISPR assay using Cas12a-induced plasmid supercoil relaxation for ultrasensitive, label-free detection of DNA targets.
