The process of functionalization in the field of nanotechnology is an important area of scientific and technical activities. Functionalization involves different expertise insofar as its complexity impacts physics, chemistry, electronics, measurement and instrumentation, and materials science. The research presented in this paper proposes criteria for verifying silica nanoparticles in terms of shape and dimensions based on processing transmission electron microscopy (TEM) images related to the nanoparticles using two techniques: monadic vision, mostly employed in robotics, and particle image velocimetry (PIV) used in fluid motion characterization through imaging. The first technique is connected to the characterization of the dimensions of objects by a robot having vision. The second, used in fluid velocimetry, is related to motion. Here, we do not deal with motion in the traditional meaning but during functionalization droplets of materials are generally seen. So droplets can be considered as quasi-motion from the main body to the outside due to centrifugal forces. In any case, both algorithms yield to shape and dimension determination for assessing the quality of functionalization.

通过 TEM 图像表征的功能化纳米粒子：两种创新技术之间的比较


纳米技术领域的功能化过程是科学技术活动的重要领域。功能化涉及不同的专业知识，因为其复杂性影响物理、化学、电子、测量和仪器以及材料科学。本文提出的研究提出了验证二氧化硅纳米颗粒形状和尺寸的标准，该标准基于使用两种技术处理与纳米颗粒相关的透射电子显微镜（TEM）图像：单子视觉（主要用于机器人技术）和粒子图像测速（PIV） ）用于通过成像来表征流体运动。第一种技术与具有视觉的机器人表征物体的尺寸有关。第二个用于流体测速，与运动有关。在这里，我们不处理传统意义上的运动，但在功能化过程中通常会看到材料的液滴。因此，液滴可以认为是由于离心力而从主体向外的准运动。无论如何，两种算法都可以确定形状和尺寸来评估功能化的质量。
