This study developed collagen-PVA hydrogel microneedles containing Aloe vera and Calendula officinalis for wound dressing. Microneedles with different Aloe vera : Calendula officinalis ratios 1:3, 1:1, and 3:1 were evaluated for swelling, mechanical strength, and antibacterial activity. Higher Aloe vera enhanced swelling, flexibility, and Escherichia coli inhibition, while higher Calendula officinalis improved tensile strength and Staphylococcus aureus inhibition. The 1:1 ratio offered the most balanced performance, demonstrating potential for effective wound healing applications.
