Transdermal immunomodulation is of increasing interest as an efficient drug delivery method. It non-invasively delivers drugs directly to skin-resident immune cells, thereby avoiding the first-pass metabolism. Herein, we prepared ovalbumin-conjugated hyaluronic acid-methacrylate (HAMA-OVA) and schizophyllan-methacrylate (SPGMA) hybrid nanogels and investigated their suitability for topical delivery. The particle size was controlled to between 100 and 300 nm using ultrasonication and filtering processes. The nanogels penetrated the porcine
