Question

living tissue seen by which scientists at first?​

Answer 1

Answer:

Live cell imaging is the study of living cells using time-lapse microscopy. It is used by scientists to obtain a better understanding of biological function through the study of cellular dynamics.[1] Live cell imaging was pioneered in first decade of the 20th century. One of the first time-lapse microcinematographic films of cells ever made was made by Julius Ries, showing the fertilization and development of the sea urchin egg.[2] Since then, several microscopy methods have been developed which allow researchers to study living cells in greater detail with less effort. A newer type of imaging utilizing quantum dots have been used as they are shown to be more stable.[3] The development of holotomographic microscopy has disregarded phototoxicity and other staining-derived disadvantages by implementing digital staining based on cells’ refractive index.
