About this collection
Worldwide, the ever-growing threat of antimicrobial resistance calls for new strategies to tackle infection that go beyond the traditional use of antibiotics. The limited pipeline of drug candidates is unable to provide new-generation antibiotics at the pace resistances are being acquired and spread amongst microorganisms. Likewise, the development of advanced technologies to prevent host colonisation and specific pathogen diagnosis are more necessary than ever. Guest Edited by Materials Horizons and Nanoscale Horizons Community Board members Ignacio Martín-Fabiani, Loughborough University, United Kingdom, and Ignacio Insua, Universidade de Santiago de Compostela, Spain, this collection showcases the most recent advances in the prevention, diagnosis, and treatment of infections using novel strategies at the interface between chemistry, physics, biology and nanotechnology.
