Summary: In this study, a novel complex coacervate between gliadin and sodium alginate was formed and successfully loaded with curcumin, demonstrating spherical particles with good homogeneity and dispersion. The formation of coacervates at different pH induced by electrostatic interaction reduced the release speed of curcumin, leading to better encapsulation and controlled release properties.

Summary: Studied the dynamics of single stranded DNA in complex coacervate droplets and micelles. Found that the diffusion coefficient of DNA depends more strongly on DNA length than predicted by traditional models, which can be partly explained by changes in complex coacervate density and other factors. Also discovered that chain length polydispersity is the main cause of a broad distribution of exchange rates in micelles, and dye interactions significantly affect micelle exchange rates.

Summary: This article describes the water-soluble superstructures of hydrophobic nanocrystals that have been developed recently, highlighting their properties and potential applications as nanoheaters. The first structure discussed is called cluster structures, which are hydrophobic 3D superlattices of Co or Au nanocrystals covered with organic molecules. These structures retain their magnetic and optical properties when dispersed in aqueous solution. The second structure is based on liquid-liquid instabilities and involves Fe3O4 nanocrystal shells filled or unfilled with Au 3D superlattices, known as colloidosomes and supraballs, respectively.

Summary: It has been demonstrated that CdS quantum dots can be synthesized and self-assembled into complex superstructures without the use of templates. These superstructures exhibit Stokes-shifted photoluminescence and a single-exponential decay behavior, indicating the presence of trap states within a narrow range. The formation of liquid crystal phases is proposed as the growth mechanism for these superstructures, supported by small-angle X-ray scattering analysis.

Summary: Through a comprehensive Monte Carlo investigation, this study demonstrates how the mechanical properties of self-assembled magnetic nanocubes can be intrinsically controlled by the nanoparticle magnetocrystalline anisotropy (MA), as well as by the superstructure shape anisotropy. Low MA-to-dipolar energy ratio favors isotropic mechanical superstructure stabilization, while a high ratio yields magnetically blocked nanoparticle macrospins.

Summary: This study evaluated the oncological outcomes of salvage PSMA-RGS in patients with recurrent oligometastatic prostate cancer and identified predictive preoperative factors for improved outcomes. The results showed that the 3-month and 2-year tumor survival rates were 32% and 58%, respectively. Preoperative PSA, number of PSMA-avid lesions, and localization of lesions were independent predictors of biochemical recurrence after PSMA-RGS.

Summary: This study investigates the impact of signal-to-background ratios (SBR) on surgical performance using kinematics analysis. The results show that below SBR 1.5, task completion time, time spent in fluorescence-imaging mode, and total pathlength increase significantly, and handling errors become more frequent. The values of Dx and DM indicate that proficiency can only be achieved at SBR> 1.55.

Summary: This study demonstrates that pathogen immunogenicity can be enhanced by complexing an adjuvant onto the surface of a poorly immunogenic bacterium. The adjuvanted bacteria were able to stimulate a stronger immune response and could potentially be used as a treatment modality to boost the immune system's response to pathogenic microbes.

Summary: Molecular imaging technologies are increasingly important in the diagnosis, monitoring, and treatment of cancer. The relevance and accessibility of surgical targets, as well as the selection of the correct combination of imaging agents for visualizing disease sites with high affinity and specificity are crucial. Developments within engineering/imaging physics continue to drive image-guided surgery, enhancing sensitivity and spatial resolution to ensure cancer sites are not overlooked during surgery.

Summary: Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful technique for molecular characterization and quantification, but is limited by poor sensitivity and expensive hardware. In this study, a microfluidic NMR-chip with a single planar-spiral microcoil and photochemically induced hyperpolarization is used for multidimensional and heteronuclear NMR experiments on picomole quantities of material. This chip significantly improves sensitivity and reduces cost and hardware complexity compared to traditional instruments.
