Change in shape factor of hydrogel microcapsules during their low-temperature formation

Original language description

Sodium alginate microcapsules are used in tissue engineering, medicine, and cryobiology due to their supportive and protective roles. Their size and shape influence the release of encapsulated substances. This study examined how the gelling solution&apos;s temperature affects microcapsule form. Using electrostatic spraying (325+-19 V/mm), 2% sodium alginate was introduced into a 15% calcium chloride solution at various temperatures. At 0oC, microcapsules (123+-36 μm diameter) showed &quot;drop-shaped&quot; deformation with a Sphericity factor of 0.83-0.66. The Grum CSF decreased by 11.27%, likely due to increased viscosity of the gelling solution at lower temperatures.
