Wang’s team proposed the use of fully integrated wearable bendable bandage and minimally invasive microneedle-based sensors modified with catechol (CAT) for rapid and decentralized screening of skin melanoma through the amperometric detection of the benzoquinone (BQ) generated in the presence of the tyrosinase (TYR) biomarker (Figure 8). Here, TYR is linked to cutaneous melanoma.
