Bacterial Viability Imaging Services

Bacterial viability detection has been widely used in the fields of biotechnology, food industry, medicine, and environmental monitoring. It has become an important indicator for evaluating antibacterial properties and monitoring microbial viability in water. Traditionally, nucleic acid staining, membrane potential, and redox indicators are often used to measure cell status indirectly to assess bacterial viability. But these methods cannot directly observe the growth and division of bacteria. In recent years, with the development of fluorescent probes and imaging technology, researchers can directly observe the morphology and growth of bacteria through microscope imaging, and then evaluate the bacterial activity.

Bacterial Viability Imaging Analysis

Due to its rapidity and the powerful ability to analyze complex samples, flow cytometry has become a popular tool for microbiology research. However, traditional flow cytometry cannot observe the morphology of each bacterial cell. With the advent of imaging flow cytometry, researchers have gained new insights into microbial phenomena that cannot be explored by traditional techniques.

CD BioSciences has been committed to the development of fluorescent probes and imaging technology for many years. We can use imaging flow cytometry to capture a clear image of each bacterial cell, and then analyze its morphological characteristics to evaluate the viability of the bacterial cell.
