There are some common applications of inverted microscopes

Cell Biology:

Cell Culture Observation: Monitoring cell growth, proliferation, morphology, and responses to treatments in real-time.  

Cell-to-Cell Interactions: Studying interactions between cells, such as cell adhesion, migration, and phagocytosis.  

Intracellular Processes: Observing dynamic intracellular processes like mitosis, meiosis, and organelle trafficking.  

Microbiology:

Microbial Growth and Morphology: Examining bacterial and fungal cultures in liquid media.

Microbial Interactions: Studying interactions between microorganisms, such as biofilm formation and predator-prey relationships.  

Materials Science:

Surface Analysis: Examining surface features of materials, such as crystal structures and defects.

Particle Analysis: Observing and characterizing microscopic particles.  

Biomedical Research:

Drug Discovery: Screening for drug efficacy and toxicity on living cells.

Immunology: Studying immune cell responses and interactions.  

Developmental Biology: Observing embryonic development and tissue differentiation.
