Article Title: On‐Site Melanoma Diagnosis Utilizing a Swellable Microneedle‐Assisted Skin Interstitial Fluid Sampling and a Microfluidic Particle Dam for Visual Quantification of S100A1

doi: 10.1002/advs.202306188

Figure Lengend Snippet: Illustration of a swellable microneedle patch and a self‐powered microfluidic device for melanoma diagnosis. i) Extraction of ISF with the administration of a swellable microneedle patch on the skin. ii) Elution in a centrifuge tube. iii) Reaction between S100A1 and antibody‐conjugated magnetic microparticles (MMPs) and polystyrene microparticles (PMPs). iv) Visual quantification of S100A1 using a microfluidic device with a microfluidic particle dam. With the high concentration of S100A1, MMPs and PMPs simultaneously bind to S100A1 to form the “MMPs‐S100A1‐PMPs” structure, which lessens the number of free PMPs escaping from a magnetic separator, resulting in a short PMP accumulation length that can be visually quantified without an additional instrument. With the lower concentration of S100A1, however, a longer PMP accumulation length is observed due to the insufficient binding between MMPs and PMPs.
