Bright field microscopy
WebBright field microscopy is the conventional technique. It is suitable for observing the natural colors of a specimen or the observation of stained samples. The specimen appears darker on a bright background. In order to increase the contrast, one should close the condenser. This will reduce the resolution, but there is a positive trade-off. WebApr 11, 2024 · Rapid and accurate identification of pathogens is crucial for public healthcare and patient treatment. However, the commonly used analytic tools such as molecular diagnostics and mass spectrometry are either expensive or have long turnaround times for sample purification and amplification. Here, we introduce electrochemiluminescence …
