Studies on in situ measurement technology of characterization of bioaerosols

在日本关东的城市地区，杉木授粉病呈上升趋势。花粉致敏种在细颗粒中大量分布，这可以解释这些致敏种是以生物气溶胶的形式从粗花粉粒中释放出来的小颗粒形式存在的。在本研究中，为了确定子花粉致敏颗粒，我们尝试采用基于表面等离子体共振原理的原位测量技术来测量空气中的致敏物质。由于生物分子与生物气溶胶相互作用的反应越来越强，因此可以确定其结合、解离、特异性、亲和力、质量行为和致敏浓度。

Japanese cedar pollinosis has been increasing in urban areas in Kanto, Japan. The pollen allergenic species distribute abundantly in fine particles which can be explained that these allergenic species are in the form of small size particles released from the coarse pollen grains as bioaerosols. In this study, in order to determine the daughter pollen allergenic particles, we try to develop the method for measuring airborne allergenic species by using in situ measurement technology based on the surface plasmon resonance principle. Since an increasing response as biomolecules interact with bioaerosols, the binding, dissociation, specificity, affinity, mass behavior and allergenic concentration can be determined.
