Nanoscopy: Nanoscale imaging

1. Introduction

Understanding of single molecules and atoms dates back from the end of 19 century when scientist developed models of mater. The power of comprehending this fascinating micro cosmos nanotechnology world arose from a series of experiments, written and oral debates among pioneering scientists (1). Some of the fundamental principles from then still stand “What you can see and understands depends on how you look at it.”
Nanoscopy as methodology refers to the known minor number of super-resolution microscopy techniques that have made possible to visualize specimens at the smaller visual length scale in comparing to the conventional light microscope. With the development of novel detection techniques, nanoscopy and nanoscale imaging have become cutting edge technology with great potential, sensibility, and widespread application. Due to exceedingly wicked analytical and diagnostic potential, nanoscale imaging applies to practical use in vitro and in vivo studies. Nanoscale imaging demonstrates computational discrimination in pathology and clinical research by measuring diffusion, chemical kinetics, concentration, mobility and to discriminate fluorophore flexibility from biomolecules orientation order from a tiny sample in a short time. (2-3).
Subcellular nanoscale biological structures are extensive studies like liver and LSEC since they represent vital organ for waste molecules, viruses, and nanoparticles. To investigate these biological phenomena of fenestration, utilization of optical resolution limit of microscopy technique is necessary. Samples must undergo series of fixation and dehydration steps which generates artifacts that need addressing since fenestration diameter varies depending on an applied microscopic technology (4). Applicability of optical resolution beyond diffraction limit enables development of several super-resolution optical methods like based upon structured illumination microscopy (SIM), point spread function (PSF) and based upon localization of individual fluorophores, referred as single-molecule localization microscopy (SMLM) (5,6). In vitro study of nanoscopy have a potential impact on fenestration dynamics to answer the critical questions regarding structure dynamics and response to environmental agents.
