Imaging is a critical aspect in the field of nanoscale design and fabrication. It allows researchers to visualize and study the structure, properties, and behaviour of nano materials and nano drugs in great detail. Imaging techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM) can be used to visualize the size, shape, and surface characteristics of nanoparticles, as well as their interactions with their surroundings. These techniques provide valuable information that can be used to optimize the synthesis and formulation of nano materials for various applications. Computational techniques can further assist researchers to understand and calculate the properties of the materials at the nano scale or even lower. Techniques such as molecular dynamics and finite element method (FEM) are being used to model material behaviour subjected to various types of loading and environments. These techniques can be used to understand and monitor the distribution and localization of nanoscale drug carriers in the body, as well as to track the release of drugs from these carriers over time. This information can help researchers to understand the mechanics of drug and carrier transfer and to optimize their design for maximum efficacy and safety.
