Abstract: Provided are methods of detecting analytes. In some configurations, the methods can employ analytes attached to a solid support or particle and affinity reagents that are attached to the solid support or particle via a flexible linker. In some configurations, the methods can employ analytes attached to a solid support or particle and solution-phase affinity reagents can be attracted to the analytes via application of a stimulus.

Abstract: The present disclosure provides a structured nucleic acid particle comprising a scaffold strand and a plurality of staple strands hybridized to the scaffold, forming a structured nucleic acid particle having a first planar structure coupled to a first protruding structure extending from a face of the first planar structure. Also, the present disclosure provides a structured nucleic acid particle comprising a scaffold strand and a plurality of staple strands hybridized to the scaffold, forming a structured nucleic acid particle having a plurality of planar faces. In some instances, the structured nucleic acid particle has six planar faces.
