Membranes from latex with propolis for biomedical applications

• We have prepared and characterized a system by natural rubber (NR) and propolis.
• The surface morphology, wettability, and antimicrobial activity were investigated.
• The membrane proposed here is a strong candidate to dressing for burns.
• NR promotes angiogenesis and propolis has antimicrobial activity.

Recent findings have confirmed the suitability of NR derivated systems for regenerative medicine, in which the angiogenic properties of the NR latex are exploited, and also in drug delivery systems. This work aimed to prepare and characterize a system formed by NR matrix and propolis extract, which was incorporated into the NR matrix. We have investigated the surface morphology, wettability, and antimicrobial activity as a function of the propolis incorporation. We have demonstrated the possibility of obtaining membranes flexible, translucent and non-adhesive. This kind of system can be more effective and less toxic for clinical applications such a burn dressing.
