Serious lung diseases and other health problems caused by tobacco consumption are becoming more and more prominent all over the world. Scavenging the excessive harmful free radicals in cigarette smoke is proven to be an effective method in reducing the above problems. Carbon-based nanozymes have been widely studied due to their ability of scavenging free radicals. Accordingly, the biochar derived from silkworm excrement was reported as a nanozyme with free radical scavenging ability. The biochar nanozyme calcination at 900 °C with better free radical scavenging abilities was loaded into commercial cigarette filters for the following free radical scavenging verification in tobacco smoke. Mouse model results reveal the lung tissue could be improved by the addition of biochar nanozyme. This work not only provides an effective approach to reduce the harm caused by tobacco but also provides potential applications to rationally realize low-cost, ease of production, and a wide variety of biochar sources.
由烟草消费导致的严重肺部疾病和其他健康问题在全球正变得越来越突出。事实证明，清除香烟烟雾中过量的有害自由基是减少上述问题的有效方法。碳基纳米酶因其清除自由基的能力而受到广泛研究。因此，有报道称源自蚕粪的生物炭是一种具有自由基清除能力的纳米酶。将在900℃煅烧后具有更好自由基清除能力的生物炭纳米酶加载到商用香烟滤嘴中，用于在烟草烟雾中进行后续的自由基清除验证。小鼠模型结果表明，添加生物炭纳米酶可改善肺组织。这项工作不仅提供了一种减少烟草危害的有效方法，还为合理实现低成本、易于生产以及生物炭来源广泛的潜在应用提供了可能。
