This cover by Leyre Pérez‐Álvarez, Erlantz Lizundia, and colleagues displays zinc oxide (ZnO) nanoparticles which have been incorporated into a biodegradable Poly( L ‐lactide) (PLLA) matrix with the aim of boosting the hydrolysis of PLLA film surfaces. The presence of ZnO nanoparticles speeds‐up the random‐scission of PLLA ester linkages, where an interesting surface nanostructuring induced by the degradation of PLLA to water‐soluble oligomers is observed. The modulation of the hydrolysis profile enables shorter surface modification times and provides an effective approach to quickly modify the polarity of polylactide surface. This work provides new insights on the design of antibacterial biomaterials with tailored surface functionalities obtained via surface hydrolysis reaction. DOI: 10.1002/app.47786
