Monitoring osmotic pressure with a hydrogel integrated optofluidic microlaser

Abstract

Osmotic pressure plays a key function in many biological systems and biointerfaces; however, it is often challenging to monitor minute osmotic changes under micron to the nanoscale. Unlike conventional methods,...

Evaluating the overall performance of immobilized particles through different crosslinking strategies and their nitrification characteristics

“…The osmotic pressure of the saline liquid was estimated using eqn (4). 30 π = ICRT where, π is the osmotic pressure (kpa); i is the number of mass points that can be generated by a “molecule” of a strong electrolyte in the solution; the mass points of Na 2 SO 4 and NaNO 3 are 3 and 2, respectively; c represents the saline liquid concentration (mol L −1 ); R represents the gas constant with the value of 8.31 kPa L/(mol K); T represents the absolute temperature (K).…”

Optofluidic lasers and their applications in biochemical sensing

“…In 2022, Jie et al presented a detection method for osmotic pressure by analyzing the OFL outputs from dye-doped hydrogel droplets encapsulated in FP microcavities. 162 Osmotic pressure plays an important role in numerous biological systems and biological interfaces. The results reveal the ability of OFLs to detect osmotic pressure and increase the potential to design on-chip sensors in cellular and body fluid environments via OFLs, providing a certain value for the development of biocellular lasers.…”
