*2.1.4. Applications*

The idea to use PLD to deposit some of the most varied materials, simple or complex structures with the purpose of obtaining thin films has been rewarded with numerous results published in the literature.

Complex oxide thin films for superconductors (YBa2Cu3O7 [30]; Ba2Co2Fe12O22 [31]), transpar‐ ent conducting oxides TCO [32–34], active mediums (Er:YAG [35]) wide bandgap electronics (ZnO doped [36]) or in conjunction with other semiconductors [37]), thin films for gas sensors based on nanostructured tungsten oxide [38, 39], CNx/Si thin heterostructures [40]; complex (As2S3)(100‐x)(AgI)x chalcogenide glass [41]; vanadium oxide thin films with various crystal structures [42]; tin oxide for detecting NO2 [43]; protective coatings and barriers (e.g., DLC [44], BN [45], TiN [46], ZrC [47], ZrN [48, 49], ZrC/TiN and ZrC/ZrN thin multi‐layers [50]; TiN biocompatible coatings (prostheses coatings [51–53]); particles for drug delivery [54]; antimicrobial coatings [55]; tissue engineering [56]; organic thin films, i.e., polymethylmeta‐ crylate (PMMA) [57–59]. For biosensor applications: CuO thin film for uric acid biosensor [60], gold‐coating of silicon microcantilever for DNA biosensors [61].
