A Review on Self‐Assembly of Colloidal Nanoparticles into Clusters, Patterns, and Films: Emerging Synthesis Techniques and Applications

Small Methods, Journal Year: 2023, Volume and Issue: 7(6)

Published: March 1, 2023

Abstract The colloidal synthesis of functional nanoparticles has gained tremendous scientific attention in the last decades. In parallel to these advancements, another rapidly growing area is self‐assembly or self‐organization nanoparticles. First, organization into ordered structures important for obtaining interfaces that extend even amplify intrinsic properties constituting at a larger scale. large‐scale using complex intricately designed nanostructures as building blocks, requires highly controllable techniques down nanoscale. certain cases, example, when dealing with plasmonic nanoparticles, assembly further enhances their by coupling phenomena. other process itself useful final application such sensing and drug delivery, amongst others. view importance this field, review provides comprehensive overview recent developments field nanoparticle applications. For clarity, self‐assembled are classified two broad categories: finite clusters/patterns, infinite films. Different state‐of‐the‐art obtain discussed detail, before discussing applications where significantly performance process.

Click Chemistry‐Based Bioconjugation of Iron Oxide Nanoparticles

Small, Journal Year: 2025, Volume and Issue: 21(11)

Published: Feb. 9, 2025

Superparamagnetic iron oxide nanoparticles (SPIONs) exhibit unique properties for diverse biomedical applications, including drug delivery and diagnostic imaging. Actively targeted SPIONs enhance to diseased sites, reducing side effects enhancing treatment efficacy. However, the development of reproducible functionalization protocols is challenged by erratic behavior in suspensions, such as agglomeration sedimentation. In this study, a method developed systematically optimized attach Fc-region antibodies onto silica-coated via click chemistry, ensuring controlled ligand orientation on particle surface. The synthesis successive modifications with organic moieties are presented resulting final conjugation targeting intercellular adhesion molecule 1 (ICAM1). This protein upregulated epithelial cell surfaces during gastrointestinal inflammation. Thermogravimetric analysis infrared spectroscopy confirm successful SPION after each modification step. Cell viability assessment indicates no adverse bioconjugated particles. Quantitative elemental reveals significantly higher concentration inflammation-induced Caco-2 cells exposed ICAM1-modified particles compared non-conjugated counterparts. Furthermore, laser scanning confocal microscopy these suggests surface interaction internalization SPIONs, underscoring their potential imaging therapy inflammatory diseases.
