Summary: We report a versatile approach to fabricate nonspherical polystyrene nanoparticles with controlled morphologies based on kinetically controlled seed-mediated polymerization. By manipulating reaction kinetics parameters, such as monomer concentration, reactant injection rate, and reaction temperature, we can direct the monomers to polymerize on selective sites of PS seeds, resulting in nonspherical nanoparticles with various thermodynamically unfavored morphologies. The formation mechanism of these nanoparticles has been systematically investigated by monitoring seed evolution during the reaction. This method has also been successfully extended to different monomer and seed systems.

Summary: Hierarchically structured polymeric colloids were rapidly produced by confined self-assembly of bottlebrush random copolymers in evaporative emulsion droplets. The internal structures of the particles developed instantaneously during the early stage of solvent evaporation due to the confinement effect and fast-assembling polymer architecture. Different particle morphologies were achieved by adjusting the volume fraction of copolymers.

Summary: Recent studies have discovered new strategies using DNA-based self-assembly to organize nanomaterials into three-dimensional arrays with specific lattice symmetries. By sequestering the nanomaterial into DNA origami frames or material voxels and coordinating them based on voxel geometry and directional interactions, different crystalline morphologies can be formed. The strength of vertex-to-vertex interactions in orthogonal directions determines the specific assembly morphology.

Summary: In this study, a microemulsion method was developed to synthesize controlled-size starch nanoparticles (SNPs). The method involved testing different formulations to prepare water-in-oil microemulsions, and the resulting SNPs were characterized in terms of size, morphology, monodispersity, and crystallinity. The method was also used to synthesize starch-based nanocomposites with superparamagnetic properties. This innovative technology shows potential for the design and development of functional nanomaterials.

Summary: Mechanical bonds have been used to construct mechanically interlocked aerogels (MIAs) with adaptivity and multifunctionality. However, fabricating MIAs with precise chemical structures and dynamic features is still challenging. In this study, we present MIAs carrying dense [2]rotaxane units, which provide stability and flexibility to the aerogel network. The chemical structure of [2]rotaxane allows for the fabrication of precise and full-scale mechanically interlocked networks using diverse solvents. Furthermore, the dynamic nature of [2]rotaxane allows for modulation of the morphologies and mechanical performances of MIAs under chemical stimuli. We hope that understanding the structure-property relationship in MIAs will contribute to the development of mechanically interlocked materials and provide new opportunities for constructing smart materials with multifunctionalities.

Summary: Superparamagnetic iron oxide nanoparticles, particularly in the form of nanoscopic aggregates, have various applications in contrast agents, biological tools, and sensors. The particle size and refractive index can be modified by coating the nanoparticles with another oxide, typically silica. Additionally, introducing mesoporous silica layers enables the nanoparticles to serve as theranostic nanoparticles and high-capacity adsorbers, as well as colorimetric sensors.

Summary: The development of specific and sensitive immunomagnetic cell separation nanotechnologies is crucial for improving cancer patient outcomes. The use of limited biomarkers for enriching circulating tumor cells (CTCs) has resulted in low CTC yields and purity. This study demonstrates that cell bound MUC16 can be effectively targeted for rapid immunomagnetic extraction of CTCs with high yield, purity, and viability. The results also provide insights into the impact of nanoparticle physical properties on the efficiency of immunomagnetic cell isolation.

Summary: The potential of liquid biopsy samples as a less invasive alternative to tissue biopsies is increasingly recognized. This study optimized the lysis reaction for extracting RNA from human melanoma cells using silica coated superparamagnetic nanoparticles. Surprisingly, the addition of sustainable surfactants did not significantly improve cell lysis or qRT-PCR sensitivity. Higher concentrations of serum albumin in the sample matrix decreased qRT-PCR sensitivity due to increased RNase activity.
