Abstract The capacity of orthogonal imaging applied to laser-backscattering for characterising antimicrobial particles based on immobilised essential oils was tested. Different particles were synthesised using various particle and oils. Samples were characterised physico-chemically and by an imaging technique. The technique recorded the generated patterns because of the laser-particles interaction during the sedimentation process. The series of images were transformed into an orthogonal image. Data extraction varied depending on the fragmentation degree of image length. After the multivariate analysis, the physico-chemical results showed variability due to particle size. That variability diminished the effect of oils for large sizes. The imaging data collected these properties, which could be used to recognise both particle size and oil type. Thus the prediction of the properties was successful. The position in the physico-chemical space of variance was also predicted. Hence this technique could complement a low-cost method to evaluate the properties of functionalised particles with oils.

激光背散射成像在植物精油功能化抗​​菌二氧化硅颗粒的物理化学表征中的应用

摘要 测试了正交成像应用于激光背散射以表征基于固定化精油的抗菌颗粒的能力。使用不同的颗粒和油合成不同的颗粒。样品通过物理化学和成像技术进行表征。该技术记录了由于沉积过程中激光-粒子相互作用而产生的图案。该系列图像被转换为​​正交图像。数据提取因图像长度的碎片化程度而异。多变量分析后，物理化学结果显示出由于颗粒尺寸的变化。这种可变性降低了油对大尺寸的影响。成像数据收集了这些特性，可用于识别颗粒大小和油类型。因此，属性的预测是成功的。还预测了物理化学方差空间中的位置。因此，该技术可以补充一种低成本的方法来评估含油的功能化颗粒的特性。
