Picture: Aqueous solution of two polymers (red and green) in test tubes and artificial cells of different sizes
New research suggests that cell size and cell membranes may play a key
Artificial cells can be small saviors, such as the COVID-19 mRNA vaccine
However, creating and manipulating these cells presents many challenges
This separation, known as liquid-liquid phase separation (LLPS), has become a fundamental mechanism for regulating the biological activity of living organisms
"Traditionally, as long as the size of the container is 1 micron or micron (one thousandth of a millimeter) or greater, the separation conditions and degree of separation are considered dimension-independent
The idea of cell size-dependent behavior was proposed in 2012, but the details of the phenomenon remain unclear
"From experiments like this, we became aware of the subtle differences between membrane-sense molecules and chose the preferred molecule, which is the origin
What's next? According to Yanagisawa, "The next step is mainly in two directions: one is the physical understanding and formulation of the effects of cell-sized spaces on molecular behavior; The other is used in pharmaceutical and cosmetic applications, taking into account the effects of cell size, using artificial cells
