In this study a comparison of scanning near-field optical microscopy with a traditional, well-known microscopic technique like transmission electron microscopy is discussed. To establish a reliable and comparable method for high-resolution scanning near-field optical microscopy imaging of biological samples, the attention is focussed on cell sections. In(More)
BACKGROUND The morphology of spermatozoa is a fundamental aspect to consider in fertilization, sperm pathology, assisted reproduction and contraception. Head, neck, midpiece, principal and terminal part of flagellum are the main sperm components to investigate for identifying morphological features and related anomalies. Recently, scanning near-field(More)
In this study, we have performed a morphological analysis of crocidolite fibres interaction with mesothelial cells (MET5A) by combining conventional electron microscopy with atomic force (AFM) and scanning near-field optical microscopy (SNOM). After 6-h exposure at a crocidolite dose of 5 μg cm(-2), 90% of MET5A cells interact with fibres that under these(More)
Newborn rat oligodendrocyte cultures were investigated by scanning near-field optical microscope (SNOM), a versatile new tool able to map cell membranes in 3D and simultaneously obtain images of the cytoplasm. Topography, error, transmission and reflection signals were acquired to describe cell morphology with nanometer-scale resolution. Oligodendrocytes(More)
