Chondroitin sulfate-based dissolvable microneedles loaded with NIR-II photothermal and natural anticancer agents for synergistic melanoma therapy.

Melanoma is characterized by its aggressiveness, high metastatic potential, and numerous mutations, which limit the effectiveness of current treatments. To address this issue, we developed a dissolvable microneedle (MN) system composed of poly(2-ethyl-2-oxazoline) (PEtOz) and chondroitin sulfate (CS). This MN system was loaded with liposomes containing both a NIR-II photothermal small molecule (IRLy) and the natural anticancer agent Gambogic acid (GA), forming Lip(IRLy + GA) MNs.

Tellurium nanoparticles and Fucoidan-loaded dissolvable microneedles for combined photothermal therapy and anti-angiogenesis in melanoma treatment.

Melanoma, an aggressive skin tumor, is prone to metastasis, significantly reducing patient survival rates once it occurs. Tumor microvascularity is a key factor in metastasis, making the inhibition of microvascular formation crucial. Emerging photothermal therapy (PTT) and microneedles (MNs) have garnered attention due to their non-invasive and controllable nature.
