Shear‐Induced Supramolecular Organization of Calf‐Thymus DNA in Solution: Insights from SAXS Coupled with Rheology

Macromolecular Symposia, Volume 414, Issue 6, December 2025.
ABSTRACT The investigation of DNA's dynamic and flow properties in solution is crucial for understanding its biological roles. DNA double helix strands interact and, at high concentrations, they form liquid crystalline phases, which are influenced by molecular weight and ionic strength. At rest, Small Angle X‐ray Scattering (SAXS) shows that DNA double

Biopolymer‐Based Nanogels Synthesis, Characterization, and Stability for Doxorubicin Encapsulation and Delivery

Macromolecular Symposia, Volume 413, Issue 4, August 2024.
Abstract Nanogels are nanostructures with dimensions within the nanoscale, composed of crosslinked polymers through their functional groups. Nanogels can display sensitiveness to stimuli, such as pH or temperature. This characteristic has been used in the design of new platforms for the transport and release of active ingredients.

Effect of DNA's Molecular Weight on their Solution Viscosity, Critical Concentrations, and Liquid Crystals Formation

Macromolecular Symposia, Volume 413, Issue 4, August 2024.
Abstract The study of the dynamics of nucleic acids in solution, their flow properties, and viscoelasticity is of great importance for understanding their biological functions. Many important properties of nucleic acids, such as DNA, depend on polymer concentration, CDNA, molecular weight (MW), rigidity, and external salt content, the latter parameter ...
