We here provide detailed insight in self-assembled complex coacervate systems exploiting gold nanoparticles for cryoTEM contrast. Nanoparticle-containing dendrimicelles are formed from fifth-generation dendrimer-encapsulated nanoparticles (DENs) and dendrimer-stabilized nanoparticles (DSNs). The complex coacervate structures self-organize in biconcave thin water layers into size-sorted monolayer superstructures. The embedded nanoparticles are a straightforward tool to visualize dendrimicelles and determine the aggregation number and polydispersity. The superstructure shows extreme size-sorting patterns which, contrary to related systems with higher generation dendrimers, consists not only of dendrimicelles but also much bigger complex coacervate nanoassemblies, such as vesicles.

Cohort Study of Oligorecurrent Prostate Cancer Patients: Oncological Outcomes of Patients Treated with Salvage Lymph Node Dissection via Prostate-specific Membrane Antigen-radioguided Surgery

Sophie Knipper, Mehrdad Mehdi Irai, Ricarda Simon, Daniel Koehler, Isabel Rauscher, Matthias Eiber, Fijs W. B. van Leeuwen, Pim van Leeuwen, Hilda de Barros, Henk van der Poel, Lars Budaeus, Thomas Steuber, Markus Graefen, Pierre Tennstedt, Matthias M. Heck, Thomas Horn, Tobias Maurer

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.

Quantifying the Impact of Signal-to-background Ratios on Surgical Discrimination of Fluorescent Lesions

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.

Chemically Enhanced Immunogenicity of Bacteria by Supramolecular Functionalization with an Adjuvant

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.

On the influence of protein aggregate sizes for the formation of solid and hollow protein microparticles

Laura M. I. Schijven, Vittorio Saggiomo, Aldrik H. Velders, Johannes H. Bitter, Constantinos V. Nikiforidis

Summary: Researchers have discovered that solid or hollow microparticles can be formed using proteins with different aggregate sizes. By mixing proteins with CaCl2 and Na2CO3 solutions, and then adding Au3+ ions, solid and hollow protein microparticles with embedded gold nanoparticles can be fabricated. This method has a broader range of applications, including biomaterial preparation and multimodal imaging.

Size-advantage of monovalent nanobodies against the macrophage mannose receptor for deep tumor penetration and tumor-associated macrophage targeting

Summary: Nanobodies (Nbs) have been identified as an elegant alternative to conventional monoclonal antibodies for cancer therapy, but there is a lack of detailed microscopic insight into the in vivo pharmacokinetics of different Nb formats in tumor-bearers, especially for the targeting of pro-tumoral tumor-associated macrophages (TAMs) located in less penetrable tumor regions.

Summary: In this study, the ability of a bacteria-specific hybrid tracer (99mTc-UBI29-41-Cy5) to visualize the bacterial load on femoral implants using clinical-grade image guidance methods was evaluated. The results showed that this hybrid tracer allowed effective bacterial staining and combined qualitative real-time fluorescence guidance with nuclear imaging for quantitative monitoring of the effectiveness of cleaning strategies.

Multinuclear 1D and 2D NMR with F-19-Photo-CIDNP hyperpolarization in a microfluidic chip with untuned microcoil

M. Victoria Gomez, Sander Baas, Aldrik H. Velders

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.

Summary: This study engineered a 'click-on' fluorescence detector that transforms standard robotic instruments into molecular sensing devices, enabling the detection of near-infrared fluorescence in a white-light setting. The detector showed promising performance in detecting blood vessels, assessing vascularization, and localizing lymph nodes during robotic surgery in pigs and human specimen evaluation.
