These are the images of poly-amide crystals grown from solution. Crystals are seen under optical microscope (lower resolution) and Scanning electron Microscope (Higher resolution). These images are an artistic capture of polymer crystals which conveys the message: “nature loves symmetry and beauty”.
These images of rat alveolar macrophages exposed to FITC doped silica nanoparticles were captured in a series through the z-plane using a laser scanning confocal microscope (Olympus). The fluorescent silica particles are packaged into phagosomes, which are distributed throughout the cell, showing that the macrophage is reaching capacity. At a certain concentration, the capacity of the macrophages to ingest particles will be overwhelmed, and their ability to remove foreign matter from the airways will be compromised.
