Article Synopsis
  • Surface ligands on semiconductor nanocrystals significantly influence their stability and properties, thereby enabling their use in various applications.
  • The study used isothermal titration calorimetry to analyze how different structural features of ligand chains, particularly in branched versus linear alkylthiols, affect the thermodynamics of ligand exchange on CdSe nanocrystals.
  • Results indicate that branched ligands exhibit lower energy release and entropy loss during exchange compared to linear ones, leading to a deeper understanding of ligand design for optimizing nanocrystal applications.

Background: T and B cell receptor (TCR, BCR) repertoires constitute the foundation of adaptive immunity. Adaptive immune receptor repertoire sequencing (AIRR-seq) is a common approach to study immune system dynamics. Understanding the genetic factors influencing the composition and dynamics of these repertoires is of major scientific and clinical importance.

Article Synopsis
  • Surface ligands on semiconductor nanocrystals (NCs) significantly influence their properties and applications.
  • Isothermal titration calorimetry directly measures key thermodynamic characteristics of ligand exchange from oleate-capped CdSe NCs to alkylthiols, revealing the impact of ligand chain length on reaction behavior.
  • Findings show that longer ligands increase reaction heat release and lower entropy, while smaller NCs exhibit greater spontaneity due to higher surface reactivity, informing future NC surface ligand design.
