Researchers have gained success in weighing a single living cell with utmost precision. Earlier this had not been possible since for measuring cell it had to be dried which caused the cell to die. Now researchers will be able to weigh samples as light as one thousandth of a millionth of a millionth of a gram in fluid state.
In this case researchers used a hollow resonator and put in the fluid sample. Surrounded by vacuum the resonator has fluid inside it and when it is pinged it causes vibration and then one can check the frequency for determining the mass. Now living cells can be kept in fluid form and measured with a high degree of accuracy. The researchers have plans for developing an advanced technique so that lighter objects could be weighed and put to use in cell biology even further.
