A small, cheap, and low-power mesh-type piezoelectric ultrasonic transducer (MPUT) from a household USB humidifier has been developed as a sonochemiluminescence generator for the first time. The ultrasonication of an MPUT facilitates the generation of reactive oxygen species to trigger sonochemiluminescence. There is no light emission of luminol without sonication. In contrast, the luminescence becomes very intense by ultrasonication using the MPUT and can be readily observed by a smart phone, enabling the visual detection of luminol without adding any coreactants. Interestingly, ascorbic acid, a common chemiluminescence quencher in the literature, increases the sonochemiluminescence in this system. As a result, a sensitive sonochemiluminescence method has been developed for the visual detection of ascorbic acid with a linear range of 1–40 μM and a limit of detection (LOD) of 0.35 μM. Moreover, the visual detection of superoxide dismutase has been achieved on the basis of its quenching effect, which has a linear range of 0.05–2.0 μg/mL and a LOD of 0.018 μg/mL. Because of its advantages of low cost, small size, and low-power consumption, the USB MPUT holds great potential in sonochemiluminescence (SCL) for the development of portable and disposable analysis devices in point-of-care testing and field analysis as well as chemical education.

基于小型，廉价且低功耗的USB网状压电超声换能器的超声发光。

来自家用USB加湿器的小型，便宜且低功耗的网状压电超声换能器（MPUT）首次被开发为超声波发光发生器。MPUT的超声处理促进了活性氧的产生，从而触发了超声发光。没有超声处理，没有鲁米诺的发光。相反，通过使用MPUT进行超声波处理，发光变得非常强烈，并且可以通过智能手机轻松观察到，从而可以在不添加任何共反应物的情况下目测检测鲁米诺。有趣的是，抗坏血酸是文献中常见的化学发光猝灭剂，可增加该系统中的超声发光。结果是，已经开发出一种灵敏的超声发光方法用于视觉检测抗坏血酸，其线性范围为1–40μM，检测极限（LOD）为0.35μM。此外，基于超氧化物歧化酶的淬灭效果，目测已实现，其线性范围为0.05–2.0μg/ mL，LOD为0.018μg/ mL。由于其低成本，小尺寸和低功耗的优点，USB MPUT在超声发光（SCL）中具有巨大的潜力，可用于在即时检验和现场分析以及化学教育。
