A Sample Purification and Preparation System for Materials Research / Un système de purification et de préparation d'échantillons pour la recherche sur des matériaux

我们需要一个样品提纯和制备系统，用于我们的材料研究。它包括一个高速超速离心机和一个冷冻干燥机。这是分别用于分离和干燥的两个基本设备，它们是我们研究的纳米粒子和聚合物纳米或微结构的合成、纯化和样品制备所必需的。我们的研究计划集中在开发先进的刺激响应型聚合物和材料，对健康、能源和环境有用。使用各种与聚合物一起功能化或负载在聚合物中的纳米颗粒，这些材料可以对光、二氧化碳(CO2)、pH或温度变化等信号做出反应，以受控的方式完成工作。我们探索了它们在光控制或二氧化碳触发的药物输送、气体检测传感器和可重复使用的催化剂中的应用。所要求的设备对于推进我们的研究是不可或缺的。

We request a sample purification and preparation system for our materials research. It consists in a high-speed ultracentrifuge and a freeze drier. These are two pieces of basic equipment for separation and drying, respectively, and they are required for the synthesis, purification and sample preparation of the nanoparticles and polymer nano- or microstructures that we study. Our research program is centered on the development of advanced stimuli-responsive polymers and materials useful for health, energy and environment. Using a variety of nanoparticles either functionalized with or loaded in polymers, these materials can respond to signals such as light, carbon dioxide (CO2), pH or temperature change, in a controlled way to accomplish a work. We explore their use for light-controlled or CO2-triggered drug delivery, sensors for gas detection and reusable catalysts. The requested equipment is indispensable for advancing our research.
