Summary
Atomic force microscopy (AFM) offers real-time, nano-resolution imaging of living cells. This review highlights AFM
Area of Science:
- Reproductive Biology
- Cell Biology
- Nanotechnology
Background:
- Atomic force microscopy (AFM) enables nano-resolution, real-time imaging of living cells in their native environment.
- AFM is a valuable tool with diverse applications across biology, including reproductive biology.
Purpose of the Study:
- To review the applications of AFM in the study of sperm cells.
- To explore how AFM contributes to understanding sperm morphology and function.
Main Methods:
- AFM imaging of unstained, unfixed spermatozoa in physiological conditions.
- Acquisition of three-dimensional images with precise topographical details.
Main Results:
- AFM reveals structural and topological features of spermatozoa.
- Identifies morphological and pathological defects in sperm cells, including head and acrosome abnormalities.
- Provides detailed analysis of sperm head chromatin structure.
Conclusions:
- AFM offers detailed 3D topographical insights into spermatozoa.
- Enhanced understanding of sperm structure can improve infertility management and contraceptive development.
