“…Both the van ‘t Hoff equation and Morse equation have been frequently employed to measure the osmotic pressure of different types of solutions [ 68 , 69 , 70 ]. However, there is an assumption that there is no interaction between the solute and solvent (ideal solution) underlying the van ‘t Hoff equation and Morse equation.…”

“…This leads to some inevitable errors when calculating the osmotic pressure of real solutions using the van ‘t Hoff equation and Morse equation [ 71 , 72 ]. For example, Salmani [ 68 ] utilized the van ‘t Hoff equation to determine the osmotic pressure of different binary liquid mixtures at various compositions and temperatures but found a significant deviation of van ‘t Hoff results from experimental data especially at higher solute concentrations. A similar discrepancy is also observed when measuring the semipermeable membrane behavior of engineered clay barriers using the van ‘t Hoff equation [ 70 ].…”

“…In addition, the van Laar equation can also be used to calculate the activity of the solvent in solutions as well. More recently, Hosseni and Ashbaugh established a framework for mapping the simulation results of osmotic force balance to the determinations of water activity [ 68 ].…”

Gaining insight into osmotic pressure and its biological implications is pivotal for revealing mechanisms underlying numerous fundamental biological processes across scales and will contribute to the biomedical and pharmaceutical fields. This review aims to provide an overview of the current understanding, focusing on two central issues: (i) how to determine theoretically osmotic pressure and (ii) how osmotic pressure affects important biological activities. More specifically, we discuss the representative theoretical equations and models for different solutions, emphasizing their applicability and limitations, and summarize the effect of osmotic pressure on lipid phase separation, cell division, and differentiation, focusing on the mechanisms underlying the osmotic pressure dependence of these biological processes. We highlight that new theory of osmotic pressure applicable for all experimentally feasible temperatures and solute concentrations needs to be developed, and further studies regarding the role of osmotic pressure in other biological processes should also be carried out to improve our comprehensive and in-depth understanding. Moreover, we point out the importance and challenges of developing techniques for the in vivo measurement of osmotic pressure.

“…It is worth noting that an effective EoS such as CPA in addition to handling phase equilibria calculation, can calculate every desired thermophysical property of the mixture such as osmotic pressure which is significantly useful for designing organic solvent reverse osmosis and organic solvent forward osmosis processes. 22 It should be noted that the aforementioned mixtures are being studied by CPA EoS for the first time and necessary details are presented.…”
