"Although dry mass
can be measured in living cells by quantitative phase microscopy
[primary source], the conversion factor between refractive index and dry mass
concentration must be known. While this factor is similar for most
globular proteins (typically varying by less than 5%), it can vary by
almost 20% for carbohydrates or lipids [primary source]. Approaches based on
vibrational spectroscopy can provide chemical composition of
living cells [11], but do not reveal the dry and wet mass." |
