The research team has developed a method to produce anti-counterfeit tags based on periodic arrays of nanopillars that can be realized on any surfaces including textiles. Both overt and covert images can be created using patterns from hydrophilic and hydrophobic nanopillars domains taking advantage of the inkjet layer-by-layer assembly. The hidden images are then visualized for authenticity verification by fogging them with human breath. By utilizing scalable nanopillar arrays from polyurethane, this technology may also be less costly than other options.This technology presents a reliable platform to make periodic, densely packed hole and pillary arrays with tunable optical and surface properties, which has many technological applications. Nanopillar technology offers a new tool to combat such large-scale economic problems such as counterfeit goods that affect the US economy. Preparation of wear-resistant nanopillar features on a wide range of common materials including fabric, glass, plastic, etc enables their wide-scale utilization capable of advancing other technologies besides counterfeit tags that include energy applications (e.g. self-cleaning durable coatings for solar cells) and biomedical technologies (e.g. anti-biofouling coatings).

该研究小组开发了一种基于纳米柱周期性阵列的防伪标签生产方法，可以在包括纺织品在内的任何表面上实现。利用喷墨逐层组装，可以使用来自亲水性和疏水性纳米柱域的图案来创建显性和隐性图像。隐藏的图像，然后可视化的真实性验证通过雾化他们与人类的呼吸。通过利用聚氨酯的可扩展纳米柱阵列，该技术也可能比其他选择更便宜。该技术提供了一个可靠的平台，可以制作具有可调光学和表面特性的周期性，密集排列的孔和柱阵列，具有许多技术应用。纳米柱技术提供了一种新的工具来打击影响美国经济的假冒商品等大规模经济问题。在包括织物、玻璃、塑料等在内的广泛的常见材料上制备耐磨纳米柱特征使得它们的大规模利用能够推进除了伪造标签之外的其他技术，包括能源应用（例如，用于太阳能电池的自清洁耐用涂层）和生物医学技术（例如，抗生物污染涂层）。
