Abstract

Brillouin Light Scattering (BLS) spectroscopy is a non-invasive, non-contact, label-free optical technique that can provide information on the mechanical properties of a material on the sub-micron scale. Over the last decade it has seen increased applications in the life sciences, driven by the observed significance of mechanical properties in biological processes, the realization of more sensitive BLS spectrometers and its extension to an imaging modality. As with other spectroscopic techniques, BLS measurements not only detect signals characteristic of the investigated sample, but also of the experimental apparatus, and can be significantly affected by measurement conditions. The aim of this consensus statement is to improve the comparability of BLS studies by providing reporting recommendations for the measured parameters and detailing common artifacts. Given that most BLS studies of biological matter are still at proof-of-concept stages and use different--often self-built--spectrometers, a consensus statement is particularly timely to assure unified advancement.

生物材料布里渊光散射显微镜共识声明。
布里渊光散射(BLS)光谱学是一种非侵入、非接触、无标记的光学技术,可提供材料亚微米级的机械特性信息。在过去的十年中,由于观察到机械特性在生物过程中的重要作用、灵敏度更高的 BLS 光谱仪的实现及其向成像模式的扩展,该技术在生命科学领域的应用日益增多。与其他光谱技术一样,BLS 测量不仅能检测被测样品的特征信号,还能检测实验仪器的特征信号,并且会受到测量条件的显著影响。本共识声明旨在通过提供测量参数的报告建议和详细说明常见伪影,提高 BLS 研究的可比性。鉴于大多数生物物质的 BLS 研究仍处于概念验证阶段,而且使用的光谱仪各不相同(通常是自制的),因此发表一份共识声明以确保统一进展尤为及时。
