Summary: Efficient FRET systems were developed by combining colloidal CdSe quantum dots (QDs) donors and BODIPY acceptors. The optimization of the distance between the organic fluorophore and the QDs through careful system engineering led to effective energy transfer in solution and solid state, with efficiencies reaching 76%. Deposition of QDs and dye as single coordinated units in solid state further increased efficiency by reducing the distance between the fluorophores to 2.2 nm, demonstrating the effectiveness of the coupling strategy.

Summary: Controlled junctions of proteins and nanomaterials have potential applications in nanobiodevice construction. Crosstalk between sequential monolayers was studied using confocal microscopy and FLIM imaging, revealing the importance of coverage and distance between monolayers. Monte Carlo computation was used to estimate coverage in sequential monolayers. Quantum dots/protein-composed systems showed higher yield than predicted due to protein reorientation on nanoparticle surface. External application of poly-L-lysines modulated resonance energy transfer yield.

Summary: In this study, a nanocomplex (NCP), AuAgNCs-CD, was prepared by self-assembling gold nanoclusters (AuNCs), silver nanoclusters (AgNCs) and carboxymethyl-β-cyclodextrin (CM-β-CD) using a one-step method. The emission of AuNCs was significantly enhanced. It was observed that FRET occurred between AuAgNCs-CD and rhodamine B (RhB) when they were combined. The presence of carbendazim (CBZ) induced an anti-FRET effect by competing with RhB and binding to AuAgNCs-CD. This phenomenon was utilized to develop a ratiometric fluorescent detection method for CBZ.

Summary: Semiconductor nanomaterials, known as quantum dots (QDs), have attracted significant interest for their excellent optical properties and potential biomedical applications. However, the presence of toxic heavy metals in conventional QDs poses a major challenge. Ternary I-III-VI QDs have emerged as viable alternatives with tunable optical properties that emit in the near-infrared region. This review discusses the recent progress in using ternary QDs in applications such as Forster resonance energy transfer (FRET), nanomedicine, optical imaging, biosensing, and multimodal imaging. It also examines the pharmacokinetics, biodistribution, and toxicity concerns of these QDs, as well as the current status, challenges, and future directions in their application.

Summary: This study investigates the degradation mechanism of blue quantum-dot light-emitting diodes (B-QLEDs) and reveals the accumulation of electrons in the quantum-dots (QDs) as the main cause of device degradation. The accumulated electrons induce the detachment of ligands and degrade the hole transport layer (HTL), while surface defects and HTL decomposition also contribute to B-QLEDs' stability.

Summary: Microbiota-based therapeutics offer innovative strategies to treat inflammatory bowel diseases (IBDs), but the clinical outcome and bacterial approach need improvement. Inspired by the benefits of probiotics, bioartificial probiotics are designed to restore intestinal microenvironment and shift the gut microbiome to an anti-inflammatory state. The bioartificial probiotic consists of E. coli Nissle 1917-derived membrane (EM) as the surface and biodegradable diselenide-bridged mesoporous silica nanoparticles (SeM) as the core. This work suggests a safe and effective nanomedicine for IBDs therapy.

Summary: As a solution to the chronic inflammation and local adiposity caused by obesity, cationic polyamidoamine (PAMAM) treatment has shown promising results in improving metabolic functions and reducing body weight in diet-induced obese (DIO) mice. The treatment involves the use of PAMAM generation 3 (P-G3) scavenger and complexing P-G3 with human serum albumin (HSA) to achieve sustained release. Local injection of HSA-PG3 successfully restricts the distribution of the complex within the targeted adipose tissue and reduces focal adiposity.

Summary: Developing magnetic ultrasoft robots requires materials with excessive deformability, responsive actuation, and rapid adaptability, which are difficult to achieve with current soft polymeric materials. We have developed a magnetically actuatable and water immiscible coacervate liquid robot based on magnetic core-shell nanoparticles. This millimeter-sized liquid robot can remain stable under changing conditions, release loaded cargoes on demand, squeeze through capillary networks within seconds, and achieve intravascular targeting guided by a magnetic field. This coacervate-based liquid robot represents a distinct design strategy for high-performance ultrasoft robots in biomedicine.

Summary: The integrity of the blood-brain barrier formed by brain microvascular endothelial cells derived from 22q11.2 Deletion Syndrome patients is compromised. The haploinsufficiency of CRKL, a gene within the 22q11.2 DS deletion region, contributes to this deficit. Treatment with imatinib, an FDA-approved drug, restores the compromised blood-brain barrier by increasing the level of active forms of the CRKL protein.

Summary: This study investigates the effectiveness of cationic hyperbranched polyaminoglycosides derived from tobramycin (HPT) and disulfide-included HPT (ss-HPT) in scavenging cell-free nucleic acids (cfNAs) to mitigate posttrauma inflammation and hypercoagulation. Both polymers demonstrate the ability to suppress inflammation and hypercoagulation by efficiently scavenging cfNAs, and exhibit potent antibacterial effects. Additionally, these polymers exhibit favorable modulatory effects on inflammation and therapeutic outcomes in a mouse model. Notably, ss-HPT shows high accumulation and retention in injured organs of traumatized mice, with a higher biodegradation rate in healthy mice compared to HPT.

Summary: Even small changes in physicochemical properties of nanoforms (NFs) can influence their environmental fate and hazard. Testing and characterizing each individual NF will not be feasible due to the large number of new materials being developed. Targeting the most relevant form of the NF for a given exposure is important for efficient risk assessment. In aquatic systems, functional fate processes play a key role in determining the exposure relevant form of NFs. Grouping of NFs and read-across based on functional fate pathways can be justified by considering the shared fate and hazard profile. A new Integrated Approaches to Testing and Assessment (IATA) is presented, focusing on dissolution, dispersion stability, chemical transformations, and the contribution to toxicity from particles and dissolved components. This IATA can be used as a template for future in vivo kinetic assessments.

Summary: Compared with vein injection, oral administration is a preferred non-invasive and self-help treatment option for cancer therapy. However, the harsh gastrointestinal tract and biological barriers limit the stability and efficiency of oral drug delivery systems. To overcome these challenges, researchers have developed Cyssome, a drug delivery platform that can maintain stability in harsh environments, penetrate biological barriers, and improve drug release and bioavailability.
