细菌、病毒等病原体给人类社会造成巨大危害。化学药剂、热能和紫外线被广泛应用于灭活有害微生物,但这些方法也会对病原体的宿主产生无差别伤害。宿主无损光照消毒技术能够在不损伤宿主细胞的同时灭活病原体,因而受到越来越多的关注。目前主流的宿主无损光照消毒技术包括207~222 nm远紫外线(far-ultraviolet C,far-UVC)、抗菌蓝光(antibacterial blue light)和低功率超短脉冲激光消毒。该文综述了这3种技术的基本原理、研究动态、适用场景和优缺点;对比了宿主无损光照消毒技术与传统紫外线消毒技术的技术特点;从理论模型建立和实际应用2方面提出了宿主无损光照消毒技术的研究展望。宿主无损光照消毒技术将有助于阻止大规模疫情中有害病原体的传播,可为食品保鲜和医疗产品消毒提供一种新方案,具有广阔的应用前景。
