摘要

背景:细菌对经典抗生素的耐药性对卫生保健环境中感染的预防和治疗提出了越来越大的挑战。引入具有活性成分的抗菌纳米涂层,通过预防性卫生方法为活性杀灭微生物提供了替代措施。目的:本研究的目的是调查一组抗菌涂料在欧洲市场上的抗菌活性。方法:对市售抗菌涂层的抗菌效率进行了比较,有偏见的选择。我们联系了供应商,要求他们提供玻璃和/或不锈钢基板上的涂料。总共收到了来自11家供应商的23种涂料,使用国际标准化组织(ISO) 22196协议研究了它们对大肠杆菌生长的影响。结果:大多数含纳米材料的涂层(n=13)含有纳米银(n=12),只有1种含光催化TiO2作为活性粒子。所有涂层之间的抗菌活性差异(用对数还原值表示)在1.3到6.6之间,而纳米材料组的差异在2.0到6.2之间。虽然纳米银涂层在攻击后平均非常有效地减少了活菌的数量,但在其基质中含有固定共价季铵盐的涂层,其对数减少幅度最大(6.6)。除了这两种化合物外,含有TiO2、聚二甲基硅氧烷、三氯生或吡啶硫锌的涂层对大肠杆菌的杀灭率为100%。结论:我们的研究结果表明纳米银在纳米颗粒基涂层中占主导地位,并且性能良好。然而,考虑到生态毒理学排放和影响的未知因素,在广泛应用于不同环境之前,需要进一步考虑。

Comparative performance of a panel of commercially available antimicrobial nanocoatings in Europe.

Comparative performance of a panel of commercially available antimicrobial nanocoatings in Europe.

Comparative performance of a panel of commercially available antimicrobial nanocoatings in Europe.

Comparative performance of a panel of commercially available antimicrobial nanocoatings in Europe.

Background: Bacterial resistance against the classic antibiotics is posing an increasing challenge for the prevention and treatment of infections in health care environments. The introduction of antimicrobial nanocoatings with active ingredients provides alternative measures for active killing of microorganisms, through a preventive hygiene approach.

Purpose: The purpose of this study was to investigate the antimicrobial activity of a panel of antimicrobial coatings available on the European market.

Methods: A comparative, biased selection of commercially available antimicrobial coatings was tested for antimicrobial efficiency. Suppliers were contacted to deliver their coatings on glass and/or stainless steel substrates. In total, 23 coatings from eleven suppliers were received, which were investigated for their effect on the growth of Escherichia coli, using the International Organization for Standardization (ISO) 22196 protocol.

Results: The majority of nanomaterial-containing coatings (n=13) contained nanosilver (n=12), while only one had photocatalytic TiO2 as the active particle. The differences in antimicrobial activity among all of the coatings, expressed as log reduction values, varied between 1.3 and 6.6, while the variation within the nanomaterial-based group was between 2.0 and 6.2. Although nanosilver coatings were on average very effective in reducing the number of viable bacteria after challenge, the strongest log reduction (6.6) was seen with a coating that has immobilized, covalently bound quaternary ammonium salt in its matrix. Besides these two compounds, coatings containing TiO2, poly(dimethylsiloxane), triclosan, or zinc pyrithione evoked 100% killing of E. coli.

Conclusion: Our findings indicate that nanosilver dominates the nanoparticle-based coatings and performs adequately. However, considering the unknowns in relation to ecotoxicological emission and effects, it needs further consideration before widespread application into different environments.
