Why coating electrodes with hydrogels?4 answersCoating electrodes with hydrogels provides several benefits. Hydrogels can prevent passivation of electrodes caused by protein adsorption, improving sensing sensitivity and accuracy in in vivo neurochemical monitoring. They can also create a robust interface between conventional electrodes and conducting polymers, enhancing the reliability and long-term stability of bioelectrodes for functional bioelectrode engineering. Additionally, hydrogels can reduce the foreign-body reaction (FBR) and fibrotic capsule formation around intraneural electrodes, improving their functionality and longevity. Hydrogels with tissue-like modulus and excellent flexibility can be used to fabricate hydrogel electrodes for acquiring high-quality physiological electrical signals, such as electroencephalography (EEG), with improved stability, low impedance, and tolerance to sweat and motion. Furthermore, hydrogel coatings, such as conductive hydrogels (CHs), can provide lower impedances and higher charge injection limits (CILs) than standard platinum electrodes, supporting safer application of smaller electrode sizes for deep brain stimulation and other neurological devices.
What is the effect of hydrogel fibers orientation on cell orientation in tissue engineering ?5 answersThe orientation of hydrogel fibers has a significant effect on cell orientation in tissue engineering. Anisotropic hydrogels, which can mimic the structure and physical properties of anisotropic tissues in vivo, provide cells with the appropriate cues for alignment. In one study, injectable alginate hydrogels containing magnetic polycaprolactone (PCL) short nanofibers were fabricated, and the alignment of the nanofibers was achieved through an external magnetic field. The results showed that the oriented hydrogels with shorter nanofibers had lower angular deflection and higher mechanical properties compared to random ones. Another study used an acoustofluidic device to pattern mammalian cells within hydrogel fibers, resulting in parallel lines of cells that mimic the structure of skeletal muscle. These patterned hydrogels showed increased formation of myotubes and spontaneous twitching of the myotubes. Additionally, a core-shell microfluidic extrusion method was used to fabricate cell-laden composite hydrogel fibers with tunable mechanical properties, enabling the formation of highly aligned cellular morphology.
