Response Surface Methodology for Optimization of Hydrogel-Forming Microneedles as Rapid and Efficient Transdermal Microsampling Tools
Leanpolchareanchai & Nuchtavorn
The finding, in our words
Optimised hydrogel-forming microneedles collected 124.6 µL of interstitial fluid with 71.8 to 78.3 percent recovery after 400 µm skin insertion, offering a minimally invasive approach for point-of-care microsampling.

The review finds that lab-on-chip liquid biopsy technologies are sufficiently mature for distanced cancer screening and follow-up, enabling patient-centric sample collection that reduces exposure risks during pandemics.

Saliva samples collected using the OMNIgene ORAL device and oral wash samples remain stable for microbiome diversity and relative abundance analyses for up to five years when stored at -80°C. This supports the use of these self-collection methods for long-term prospective biobanking and decentralised clinical studies.

Volumetric absorptive microsampling showed better precision than dried blood spots and a metabolic profile closer to whole blood, with stable signalling lipids for 24 hours at room temperature but significant changes after one week unless stabilised, indicating feasibility for decentralised sampling with the need for storage strategies.

Midstream urine self-collection demonstrated adequate sensitivity for Chlamydia trachomatis screening in asymptomatic patients, although it was less sensitive than vaginal swabs in women, and the study confirmed that nucleic acids in neat urine remain stable for up to seven days when stored at 4°C.

This study found strong agreement between self-collected urine samples tested with the INDICAID HPV assay and clinician-collected swabs tested with the BD Onclarity assay for detecting high-risk HPV. The results suggest that urine-based self-collection offers a reliable alternative for cervical cancer screening, potentially improving access for women who face barriers to standard care.
