Yes, electron microscopes are expensive. Electron microscopes are sophisticated scientific instruments that use electron beams to achieve extremely high magnification and resolution, allowing researchers to observe objects at the nanoscale. The technology and precision required in electron microscopes contribute to their high cost. These instruments often involve complex components, including electron sources, electromagnetic lenses, detectors, […]

Under a microscope, a kidney stone typically appears as a crystalline structure with various shapes and sizes, such as jagged edges or smooth surfaces, depending on the composition of the stone. Kidney stones are formed from accumulating substances in the urine, such as calcium, oxalate, and phosphate. These substances can crystallize and aggregate, leading to

Under a microscope, nail fungus (onychomycosis) typically appears as hyphae (thread-like structures) invading and spreading within the nail tissue. Nail fungus is primarily caused by dermatophyte fungi, commonly Trichophyton rubrum, Trichophyton mentagrophytes, or Candida species. When observed under a microscope, these fungi exhibit distinctive characteristics. The hyphae, which are branching filaments, penetrate and invade the

Chlamydia is a bacteria that cannot be seen with the naked eye. Under a microscope, Chlamydia appears as small, round, or oval-shaped cells. Chlamydia trachomatis is an obligate intracellular bacterium, meaning it can only survive and replicate inside host cells. When observed under a microscope, Chlamydia cells typically appear as small, gram-negative, cocci or rod-shaped
