Realizing microrheological response of configurable viscoelastic media with a dynamic optical trap

Key Points

• The aim is to explore how changes in the local viscoelastic environment affect microsphere movement and dynamics.
• Utilized a dynamic optical trap to manipulate microspheres in varying viscoelastic environments.
• Analyzed the response of embedded microspheres to changes in local viscoelastic properties.
• Significant alterations in microsphere motion were observed with varying viscoelastic properties.
• Identified specific dynamical phenomena linked to the viscoelastic environment.
