With life science research development and its efforts to reveal more and more ultrastructural detail, imaging methods need to cover a broad spectra of demanding applications. Recent investigations of cell morphology, development of biocompatible materials, tissue engineering research, microbiology, pharmacology, food and cosmetic studies rely on advanced imaging techniques. The dominant characteristic features for the majority of life-science specimens are their high water content, non-conductivity and sensitivity to the electron beam.
TESCAN develops and manufactures state-of-the-art scanning electron microscopes (SEM) designed to fit the needs of numerous life science applications. Using TESCAN CLARA equipped with field emission Schottky cathode, BrightBeam™ column and a powerful and versatile detection system, the investigation of detailed morphological structures as well as the ultrastructure of non-conductive biological specimens has become a straightforward procedure. Even with extremely low accelerating voltages and beam currents, fine structures of delicate specimens can be visualized. When equipped with cryo workflow, TESCAN CLARA represents a state-of-the-art scanning electron microscope for everyday experiments in life science laboratories.
Bacterial cellulose is pure, biocompatible and highly versatile material. It can be combined with various biopolymers and micro and nanoparticles in order to be used in a wide range of applications including food industry, medicine, commercial and industrial products and other fields. To be able to visualize the ultrafine network of nanocellulose fibrils, low beam voltages and beam currents need to be used to obtain high resolution images of such a nonconductive and charging specimen.
