Particulate matter (PM) in buildings are mostly sourced from the transport of outdoor particles through a heating, ventilation, and air conditioning (HVAC) system and generation of particle within the building itself. We investigated the concentrations and characteristic of indoor and outdoor particles and airborne bacteria concentrations across four floors(More)
A mechanical pencil lead (MPL), an easily obtainable carbon-based material with a consistent size, was used as a frame to construct an MPL-supported carbon nanotube/Au nanodendrite (MPL-CNT/AuND) sensor through simple electrodeposition of Au onto the MPL in the presence of CNTs. A nanodendrite structure was adopted to ensure large numbers of active(More)
OBJECTS The prevalence of asthma has increased in recent decades globally. The objective of the present study is to elucidate whether hospitalization for bronchiolitis in infancy and low socioeconomic status interact for bronchial hyperreactivity during teenage years. METHOD We studied 522 children age 13-14 years attending schools in rural and urban(More)
Discriminating the minute content of chemicals both in precise and concise way is to use core technique for detecting water pollution. Recently a novel virus-based sensor system functionalized by M13 bacte-riophage-based structure got great attention. This system can detect various chemicals in superior sensitivity and selectivity. The filamentous and(More)
