Summary: A novel Lamb wave resonator with fully suppressed acoustic radiation in water is proposed for high-resolution mass-sensitive detection of biomolecules. The elimination of acoustic radiation is achieved by slowing down the Lamb wave to a velocity lower than the sound speed in water, enabling high-quality factor resonance and reducing sensing frequency noise. High aspect ratio electrodes are used to slow down the Lamb wave, enhancing mass sensitivity and overall sensing resolution.

Summary: A new approach for analyzing the volumetric fraction of different components in biofuel samples is proposed, using new independent features extracted based on multiharmonics measurement of frequency and amplitude variations of the transmission response of a resonator.

Summary: NiCo2O4/CF composites with strong absorption capacity, wide effective absorption bandwidth, low filling, lightweight and thin thickness were synthesized in this study. The composites showed excellent microwave absorption properties due to the synergistic effect of dielectric loss and magnetic loss, good impedance matching characteristics and more Debye relaxation processes. This provides important guidelines for the structure and component design of lightweight microwave absorbing materials.

Summary: Existing MRI reference objects are constructed from liquid or gel solutions in containers with specific geometric configurations for stability. However, there is a need for phantoms that mimic human anatomy without barriers between tissues. We created a 3D model of the brain that mimicked the relaxation properties of white and gray matter, but some flaws were visible. The stability and construction process of this anatomically representative phantom were studied.

Summary: The study revealed that calix[4]pyrroles can accelerate the vibrational energy redistribution of azide ions through hydrogen bonding interactions and restrict the rotational dynamics of the bound ions. Furthermore, they are capable of capturing azide ions in solution, but may not necessarily undergo a conformational change to a conelike geometry.

Summary: The intrinsic heterogeneity of many nanoformulations poses challenges in characterizing them at both the single particle and population levels. However, the development of advanced techniques, such as label-free single particle automated Raman trapping analysis (SPARTA), can provide valuable information in understanding and describing nanomedicine heterogeneity. This technique allows for simultaneous measurement of the nanocarrier and cargo, enabling the characterization of loading and release heterogeneity in nanomedicines.

Summary: This study describes a simple method for obtaining colloidally stable and low-fouling semiconducting polymer nanoparticles (SPNs) by grafting poly(ethylene glycol) (PEG) onto the polymer backbone. The functionalized SPNs can be specifically targeted to HER2-positive cancer cells by site-specifically clicking anti-HER2 antibodies, antibody fragments, or affibodies onto the SPN surface. In zebrafish embryos, the PEGylated SPNs show excellent circulation efficiency and the affibody-functionalized SPNs exhibit specific targeting towards HER2-expressing cancer cells in a xenograft model. This covalent PEGylated SPN system holds great potential for cancer theranostics.

Summary: Nanozymes are nanosized materials that have catalytic properties similar to biological enzymes, making them promising candidates for clinical sensing devices. They can amplify signals in nanosensor-based platforms and improve sensor detection limits. Recent developments have led to highly effective nanozymes that can detect clinically relevant biomarkers, but there are hurdles to overcome before they can be used in clinical diagnostics. This overview discusses the current understanding of nanozymes for disease diagnostics and biosensing applications, and the challenges that need to be addressed for their translation into clinical tests.

Summary: This study presents one of the geometrically simplest two-dimensional chiral metasurface platforms by arranging achiral dielectric rods in a square lattice and creating chirality through rotating individual meta-atoms. The chiroptical responses obtained from this design are stronger or comparable to more complex designs. Additionally, it is found that the resonances dependent on the arrangement are robust against geometric variations and exhibit similar behavior in experiments and simulations.

Summary: This article presents a simple method for the direct synthesis of transfer-free, nanopatterned epitaxial graphene on silicon carbide on silicon substrates. By using common lithography and lift-off techniques, a catalytic alloy tailored for optimal SiC graphitization is patterned to form planar graphene structures on top of an unpatterned SiC layer. The method is compatible with both electron-beam lithography and UV-lithography, enabling the realization of graphene gratings with a minimum width/space of at least 100 nm at the wafer scale. The resolution is limited by the flow of the metal catalyst during the liquid-phase graphitization process, but it can be further improved through optimization of the metal deposition method and lift-off process.

Summary: In this study, the properties of the on-chip hollow-core microgap waveguide in the context of optofluidics were investigated. The waveguide allows for intense light-water interaction and has fast response times. Various absorption-related experiments demonstrated the spectroscopic capabilities of the nanoprinted waveguide, and time-resolved experiments showed improved diffusion times due to the lateral access provided by the microgaps. Overall, the microgap waveguide represents a promising pathway for on-chip spectroscopy in aqueous environments.
