Researchers have developed a novel use of Raman spectroscopy Renishaw solutions in the safety assessment of sperm.He said the ANF membership now stands at more than 192,000 members and is likely to reach 200,000 members by Christmas.
A non-destructive method of DNA testing of semen is needed. Using the Raman microscope inVia, research groups at the universities of Edinburgh and California are trying to develop exactly that experimenting on live spermatozoa. After immobilization of the sperm with a flickering very focused laser beam , which can then be analyzed by Raman spectroscopy. Says Dr. Alistair Elfick homing ‘, the flexibility of both the system and Renishaw inVia staff was crucial for us to customize the tool for integrating optical tweezers.’ The resulting Raman spectra contain information about the vibrations of molecules in semen, and can be used to assess the state of its DNA. best sperm could then be selected for IVF treatment, maximizing the chance of fertilization success and can lead to more couples happy.
The inability to have children creates a great pain for many couples. The most common cause is male, usually characterized by low mobility sperm with which the genetic material is often damaged.
Unfortunately, the damage to DNA in sperm cells is difficult to detect, and most of the techniques that can identify the sperm must be broken before the chemical analysis, thus destroying the sperm.
