Amorphous titania (a-TiO2) and amorphous titania\/chitosan complexes (a-TiO2\/\/CS) were the selected bactericidal agents. Nanoparticles (NPs) and films were the two paths designed. Cotton textiles were impregnated with a-TiO2-based NPs or coated with a-TiO2 films. Industrial impregnation\/coating will be implemented during the textile finishing treatments. A novel (room temperature and base-catalyzed), green (hydrothermal water as a catalyst), time-saving, and easy scale-up sol\u2013gel process was established to produce the a-TiO2-based NPs. Amorphous-TiO2 films were produced by a dip-in (acid catalyzed) sol\u2013gel solution. The daylight bactericidal performance (without the need of an external ultraviolet light source) of a-TiO2 NPs, films, and impregnated\/coated textiles was proven according to AATCC 100 and ASTM E2149, using Staphylococcus aureus (ATCC\u00ae6538TM) as the bacterial indicator strain. A bacterial reduction of 99.97% was achieved for the a-TiO2 films and of 99.97% for the a-TiO2\/\/CS NPs. Regarding the impregnated textiles, a bacterial reduction of 91.66% was achieved with a-TiO2\/\/CS NPs, and 99.97% for cotton textiles coated with an a-TiO2 film.<\/jats:p>","DOI":"10.3390\/molecules24101891","type":"journal-article","created":{"date-parts":[[2019,5,17]],"date-time":"2019-05-17T11:06:46Z","timestamp":1558091206000},"page":"1891","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Daylight Bactericidal Titania Textiles: A Contribution to Nosocomial Infections Control"],"prefix":"10.3390","volume":"24","author":[{"given":"Joana C.","family":"Matos","sequence":"first","affiliation":[{"name":"Departamento de Engenharia Qu\u00edmica, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"},{"name":"CQE, Centro de Qu\u00edmica Estrutural, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"}]},{"given":"Cl\u00e1udia","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Departamento de Biologia, CESAM, Universidade de Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"given":"M.
