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.
