Summary: A hybrid antibody biosensor based on graphene oxide-coated gold nanoparticles was developed for fast, specific, and high sensitivity foodborne bacterial detection. The biosensor showed colorimetric and spectrophotometric changes up to 10(3) and 10(2) CFU, respectively, when incubated with Escherichia coli and Salmonella typhimurium for 5 minutes. Immobilized antibodies on the hybrid nanoparticle biosensor were specific to bacteria and exhibited specific photoablation of bacteria upon infrared exposure. This antibody-functionalized biosensor allowed for rapid optical detection and extermination of foodborne bacteria.

Summary: A dual-targeting nanomedicine composed of pH-sensitive superparamagnetic iron oxide core-gold shell SPION@Au, chitosan (CS), and folate (FA) was developed for doxorubicin (DOX) antitumor medication. The nanocomposite exhibited elevated drug loading behavior and sustained drug release capacity, with long-term anti-cancer efficacy shown in SkBr3 cell lines. In vivo results demonstrated significant tumor size reduction in treated mice, indicating the potential of this formulation for clinical breast cancer treatment.

Summary: The modification of Magneto-optic Faraday Rotation (MFR) based on Surface Plasmon Resonance (SPR) of noble metal nanoparticles (NP) has been an exciting field of research. In this study, MFR measurements were conducted in magnetoplasmonic colloidal mixtures and a spectacular plasmonic enhancement of MFR was observed for the first time. The concentration of the participating systems had a strong influence on the Langevin-type MFR patterns, and a mutually dependent optimum concentration was required to achieve MFR enhancement.

Summary: Intracerebral hemorrhage (ICH) is a significant cause of morbidity and mortality worldwide, and surgery remains the most effective way to remove ICH. However, surgery brings potential risks such as brain tissue damage, post-operative infection, and difficulty in removing deep hematoma, which are the main problems in the surgical treatment of ICH.

Summary: SARS-CoV-2 has caused a pandemic of COVID-19, and some patients have acquired secondary infections such as black fungus disease. Prompt diagnosis and treatment are necessary to prevent high mortality and morbidity rates. Uncontrolled diabetes and immunosuppression are major risk factors, and the use of steroids can increase the risk of black fungus infection. Novel and effective antimicrobial agents are needed to combat this infection.

Summary: We developed a robust method to visualize the fluidity of the inner mitochondrial membrane in living cells using a cell-permeable fluorescent molecular rotor. Our study revealed that the fluidity of the inner mitochondrial membrane is linked to cellular respiration and responsiveness to stimuli, and modulating this fluidity can support enhanced respiratory flux.

Summary: Environment-sensitive molecular probes are used for a comprehensive mapping of the complex cellular milieu. A new strategy involving multiplexing highly sensitive, spectrally tuned fluorescent dyes is presented for sensing cellular microenvironment, enabling two-color, two-dye imaging of the mitochondrial microenvironment. Multiplexed dye imaging allows the quantitative imaging of mitochondrial membrane order and cellular microenvironment, revealing dynamic heterogeneity with distinct spatiotemporal signatures.
