Recent Updates on Blood Purification: Use of Smart Polymer Materials

Journal of Biomedical Materials Research Part A, Journal Year: 2025, Volume and Issue: 113(3)

Published: Feb. 24, 2025

Blood purification is indispensable in addressing various conditions such as liver dysfunction, autoimmune diseases, and renal failure whereby toxins have to be cleared from the bloodstream effectively. Conventional methods that involve hemoperfusion, hemodialysis, hemofiltration possess several weaknesses, including loss of plasma components inefficient clearance high molecular weight solutes. This review explores current developments blood techniques particularly stimuli-responsive polymers for use extracorporeal therapy among other applications. Many aspects engineering are described terms their role removal small soluble molecules techniques. The development systems has introduced a new paradigm by enabling selective, on-demand control polymer parameters response external stimuli temperature, pH, electrolytes, light. Such advanced materials been demonstrated potential toxin clearance, minimizing thrombosis, improving compatibility antifouling, which far much better than traditional approaches. Furthermore, presents perspective on could used developing novel future medical purposes.

Chemically and biochemically responsive liquid crystal polymer networks and elastomers

Polymer International, Journal Year: 2023, Volume and Issue: 72(11), P. 977 - 983

Published: June 13, 2023

Abstract Chemically responsive liquid crystal (LC) based polymers can change their mechanical or optical properties when exposed to chemical triggers. The anisotropy inherent in LC materials allows the programming and control of predictable changes shape, stiffness, and/or color. By further incorporating ionizable moieties into polymer formulation, these may exhibit a response stimuli such as pH, solvents, specific analytes. This mini‐review highlights seminal papers recent advances use chemoresponsive for sensing actuation. We also discuss how respond biochemical through immobilization enzymes network, provide examples different types responses (e.g., shape reconfigurations color transitions). Multiple ways modulating response, gating enzyme patterning, are reviewed. Finally, we illuminate some challenges opportunities state‐of‐the‐art applications, including shape‐controllable medical implants real‐time field‐deployable sensors. © 2023 Society Industrial Chemistry.
