Engineered structural oligo formats — circular, branched, and dendrimer oligonucleotide constructs for enhanced stability, multivalency, and specialized molecular function.
Advanced oligonucleotide architectures extend beyond conventional linear oligos to include topologically and structurally engineered constructs such as circular oligonucleotides, branched oligonucleotide constructs, and dendrimer oligonucleotide constructs.
These non-linear and multicomponent formats can support improved nuclease resistance, multivalent binding, structural organization, and functional amplification across therapeutic, diagnostic, nanotechnology, and advanced bioconjugation applications.

architecture design platform
Advanced oligo design with control over topology, arm number, modular linkage, and construct complexity to support specialized structural and functional requirements.
Circular
Closed-loop
Improved stability and end-protection
Branched
Multi-arm
Higher functional density and avidity
Dendrimer
Highly branched
Dense presentation and iterative growth
Circular oligonucleotides are covalently closed constructs without free 5′ or 3′ ends. This topology can improve exonuclease resistance, structural persistence, and compatibility with specialized amplification or therapeutic designs.
Discuss Circular Oligos →
Branched oligonucleotide constructs contain multiple oligo arms extending from a central branching core. These formats can increase local functional density, support multivalent interactions, and enable advanced probe or delivery designs.
Discuss Branched Constructs →
Dendrimer oligonucleotide constructs are highly branched, iterative architectures that support dense oligo display, multivalent interaction, and advanced structural organization for specialized therapeutic, diagnostic, and nanotechnology applications.

This summary table helps distinguish the three major architecture formats by structural feature and common design value.
A typical workflow begins with defining the structural objective, selecting construct topology, optimizing linkage strategy, and evaluating performance.
Figure: Development of advanced oligo architectures typically starts with topology selection, followed by construct design, linkage and functionalization planning, and downstream evaluation of structural and biological performance.
Circular and engineered architectures can provide improved resistance to degradation and better persistence under challenging conditions.
Branched and dendrimer formats can increase local oligo presentation, multivalency, and cooperative interaction potential.
Architecture can be matched to probe design, capture systems, nanotechnology platforms, therapeutic constructs, or specialized structural applications.
Advanced oligonucleotide architectures are non-linear or multi-component oligo formats such as circular, branched, and dendrimer constructs designed to provide enhanced stability, multivalency, or specialized function.
Circular oligonucleotides are useful for improved resistance to exonuclease degradation, structural stability, and applications such as rolling circle amplification or specialized therapeutic design.
Branched oligonucleotide constructs are used to create multi-arm or multivalent structures for increased functional density, binding avidity, and advanced probe or delivery system design.
A dendrimer oligonucleotide construct is a highly branched, iterative oligo architecture designed for dense display, amplified interaction, and advanced molecular organization.
Yes. Circular, branched, and dendrimer constructs can be combined with labels, linkers, targeting motifs, or other specialized modifications depending on the application.
The best architecture depends on whether the main objective is enhanced stability, multivalent display, dense presentation, amplification, or specialized structural performance.
