Aluminum based reflective nanolens arrays were developed via a series of aluminum electropolishing and anodization steps with subsequent selective dissolution of anodic aluminum oxide (AAO). The diameter of nanolenses (d) on arrays can be controlled by altering electrolytes and voltages used for aluminum anodization. The d values of arrays produced by anodization in 0.3 M oxalic acid at 40, 60, and 80 V, and in 1.0 M phosphoric acid at 100, 110, and 120 V were 71.94, 121.90, and 161.53 nm, and 220.16, 252.06, and 274.78 nm, respectively. The effectiveness of UV (254 nm) inactivation of Escherichia coli O157:H7 and Listeria monocytogenes at concentrations of 5–6 log CFU/mL in water and in a 10% (w/v) sucrose solution was improved using a nanolens array having a d value of 252.06 nm.

铝基反射纳米透镜阵列是通过一系列铝电抛光和阳极氧化步骤开发的，随后选择性地溶解了阳极氧化铝（AAO）。可以通过改变用于铝阳极氧化的电解质和电压来控制阵列上的纳米透镜（d）的直径。在40、60和80 V的0.3 M草酸中以及在100、110和120 V的1.0 M磷酸中阳极氧化产生的阵列的d值为71.94、121.90和161.53 nm，以及220.16、252.06，和274.78 nm。紫外线（254 nm）灭活大肠杆菌O157：H7和单核细胞增生性李斯特菌的功效使用具有d值为252.06 nm的纳米透镜阵列，可以在浓度为5–6 log CFU / mL的水中和10％（w / v）蔗糖溶液中改善蔗糖溶液的浓度。
