<qa>  What is the unique microvillous structure of TheraGauze ideal for theThe goal of this study is to demonstrate safety and tolerability of a novel antimicrobial wound dressing, Antimicrobial TheraGauze. The unique microvillous structure of TheraGauze is ideal for the development of an antimicrobial wound dressing. In vitro testing has demonstrated that tobramycin is an ideal compound for integration into TheraGauze providing excellent killing of MRSA and other organisms that commonly cause wound infections. Tobramycin is a non-absorbable aminoglycoside that will be contained solely to the wound bed preventing any potential for systemic toxicities. In vivo testing of tobramycin-impregnated TheraGauze used in mouse wound models has confirmed no systemic absorption of tobramycin as demonstrated by undetectable blood levels. TheraGauze has been commercially available for 10 years as a wound dressing. Tobramycin has been available for many years as a topical antibiotic as eyedrops and as an inhaled antibiotic for patients with cystic fibrosis, demonstrating excellent safety in both cases.
