Established in 1975 in the aftermath of the OPEC oil embargo, the Strategic Petroleum Reserve was originally intended to hold at least 750 million barrels of crude oil as an insurance policy against future supply cutoffs. Today's design capacity is 714 million barrels. An approved mechanism for acquiring crude oil is through direct purchase.

Surface Plasmon Resonance (SPR) is an optical technique used to measure molecular interactions in real time. SPR can occur when plane-polarized light hits a metal film under total internal reflection conditions. SPR signal is directly dependent on the refractive index of the medium on the sensor chip.

2024年1月31日 · SPR，即表面等离子共振 (Surface Plasmon Resonance, SPR)，简单来说，它通过检测生物传感芯片上配位体与分析物之间的相互作用情况，进而探测物质的性质和结构。 通过这一技术，我们能够实时、精准地分析样品中的分子、蛋白质、DNA 等各类有机、无机物质，为科研、工业生产和医学诊断等领域带来了巨大的帮助，但是 SPR 可不是一项新技术哦！ 1902 年，科学家 Wood 在光学实验中首次发现了 SPR 现象。 经过百年的理论补充、技术迭代，目前 SPR …

测量药物分子与靶标之间相互作用强度的方法有很多，包括NMR（核磁共振）、MST（微量热泳动）、 ITC （等温滴定量热）、荧光偏振以及我们要介绍的SPR，表面等离子共振技术。 首先为大家介绍SPR技术的基本原理。 SPR现象早在1902年由 Wood 发现，他观察到当电磁波射向金属表面时，其反射光谱会产生异常，表现为在特定角度下反射光强度明显下降，光谱上出现明显的暗带。 而且金属膜表面折射率的变大会导致暗带位置发生变化。 直到1968年才对此现象提出了合 …
