生物纳米颗粒和微粒介绍

生物纳米颗粒和微粒是指粒径范围为 1-1000 纳米的微粒群（如细胞、病毒、囊泡），其中包括细菌、藻类、浮游生物、病毒、染色体以及胞外囊泡（含肿瘤囊泡、外泌体和微泡）。越来越多的科学家正致力于胞外囊泡/外泌体的功能性研究，比如将其作为非侵入性生物标志物用于某些特定性疾病和癌症的早期诊断；又或是利用其在特定的细胞间进行物质运输，从而控制相应的细胞基本功能，可以作为一种潜在的药物递送载体。海洋科学家能够利用超高灵敏度的仪器来测定浮游植物种群之间的细微差异，在遗传表征之前进行海洋病毒的可视化表证。

Extracellular Vesicles for ‘Liquid Biopsy’ Development in Cancer by Dr. Karla Williams Using nano-scale flow cytometry, the Williams lab has identified a secondary bio-marker that allows them to identify the most critical prostrate cancer in patient samples. This revolutionary discovery has the potential to reduce unnecessary needle biopsy surgeries because only a blood sample is needed, as well as reduce overall costs to test for the disease. The Williams lab expects to move to clinical trial phase in the coming months.

Large Scale Purification of RNA and RNA-based Nanoparticles by Preparative Ultracentrifugation Webinar from Daniel Jasinski covers RNA nanotechnology in cancer therapy. RNA/RNA-based nanoparticle purification by ultracentrifugation including current technologies, different methods of ultracentrifugation, why large quantities of RNA are needed, methods for large-scale RNA purification.
Looking Under the Hood: Getting Started with the Optima AUC In the webinar we discuss the fundamentals of analytical ultracentrifugation and look at a few sample applications.
Webinar: An Intro to Characterization of Biomolecules Using AUC Analytical Ultracentrifugation (AUC) is one of the most powerful biophysical tools used today for the characterization of biological samples ranging from small drug molecules to intact viruses, vesicles and microparticles
