Biodegradable Polymers for Micro Elastofluidics

Abstract

Micro elastofluidics is an emerging research field that encompasses characteristics of conventional microfluidics and fluid‐structure interactions. Micro elastofluidics is expected to enable practical applications, for instance, where direct contact between biological samples and fluid handling systems is required. Besides design optimization, choosing a proper material is critical to the practical use of micro elastofluidics upon interaction with biological interface and after its functional lifetime. Biodegradable polymers are one of the most studied materials for this purpose. Micro elastofluidic devices made of biodegradable polymers possess exceptional mechanical elasticity, excellent bio compatibility, and structural degradability into non‐toxic products. This article provides an insightful and systematic review of the utilization of biodegradable polymers in digital and continuous‐flow micro elastofluidics.

Liquid marbles: review of recent progress in physical properties, formation techniques, and lab-in-a-marble applications in microreactors and biosensors

“…While recent microfluidic devices have many gimmicks for complex material synthesis and analysis, they require the formation of specific fine microfluidic channels through dry processing and the use of high injection pressure to pump fluids. 127 Moreover, the wastage of processed channels may lead to an environmental burden. Recently, the research field studying microfluidics and fluid-structure interactions, namely micro elastofluidics, has greatly developed.…”

Calcium alginate elastic capsules for microalgal cultivation

“…In addition, the shell or the matrix can be engineered to become transparent and semi-permeable, allowing for light penetration, gas exchange, and diffusion of molecules. [13][14][15] As a result, these platforms represent favourable environments for the encapsulation and growth of diverse cell types, including microalgae. Recently, our team made a successful attempt in capturing and cultivating microalgal cells inside liquid marblea typical digital micro elastouidic platform with a porous shell made of micro/nanoparticles.…”

Calcium Alginate Core–Shell Liquid Beads Encapsulated with Microalgae for Wastewater Treatment

“…Sodium alginate liquid beads can be engineered as carriers to encapsulate and deliver various cargos such as drugs, enzymes, and ointments. [13][14][15] Sodium alginate liquid beads can also be utilized for encapsulating and promoting the sustainable growth of cells, owing to the inherent unique features of hydrogel structures, including exceptional transparency and semipermeability. The efficacy of alginate liquid beads in culturing human cells has been substantiated by numerous researchers, solidifying the status of alginate liquid beads as a safe and reliable cell culture platform.…”
