生物传感器和生物成像

生物传感和生物成像技术可协助研究人员在分子水平上研究生命体系的生物和病理过程。生物传感器是一种用于检测生物分析物的存在或浓度、生物结构或微生物的方法。它们可用于检测生物电子学、食品和环境监测、生物医学应用中的病原体、食品毒素和疾病生物标志物。
生物传感器包括三个主要部件:识别分析物并产生信号的识别元件,信号传感器,以及测量并量化接收的信号的读取器。抗体、核苷酸、酶或蛋白质等生物受体可以用作能够与目标分析物或生物标志物结合或相互作用的识别分子。信号传感器通过多种不同的物理化学特性起作用,包括电子、电化学、光学或磁性输出信号。
生物成像是一种光学形式的生物传感,用于构建细胞、组织和解剖学中生物过程的非侵入性视觉图像,从而实现更准确的疾病诊断和治疗。
推荐类别
用于活体应用的诊断成像方法包括X-光、计算机体层摄影(CT)、磁共振成像(MRI)和fMRI、正电子发射计算机断层扫描(PET)。体外应用通常包括超高分辨率双光子荧光激发显微术、光漂白荧光恢复(FRAP)和荧光能量共振转移 (FRET)技术。

- Professor Ebrahimi and Professor Robinson (Pennsylvania State University, USA) summarize recent advances in the synthesis of these 2D materials, resulting material properties, and related applications in biosensing of neurotransmitters, metabolites, proteins, nucleic acids, bacterial cells, and heavy metals.
- Graphene has emerged as the new wonder material. Being only one atom thick and composed of carbon atoms arranged in a hexagonal honeycomb lattice structure, the interest in this material has exploded exponentially since 2004 when it was first isolated and identified using a very simple method.
- Developed in the last several years, fluorescence quenching microscopy (FQM) has enabled rapid, inexpensive, and high-fidelity visualization of two-dimensional (2D) materials such as graphene-based sheets and MoS2.
- We presents an article concerning the applications of high-purity single-walled nanotubes in electronic and biomedical fields.
- Dextran is a polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(1-6) linkages. The remaining a(1-3) linkages account for the branching of dextran. Conflicting data on the branch lengths implies that the average branch length is less than three glucose units. However, other methods indicate branches of greater than 50 glucose units exist.
