DNA origami, a promising branch of structural DNA technology, refers to the technique of folding a single-stranded DNA scaffold into well-defined nanostructures. In recent years, DNA origami nanostructures have shown considerable promise in a variety of biomedical applications, owing to their biodegradability, unique programmability, and addressability. Despite their popularity, the biomedical application of DNA origami techniques, which exploits their unique programmability and addressability, is rare in previous studies. Most recently, mounting evidence has demonstrated the robustness of DNA origami nanostructures in the spatial organization of functional components at the nanoscale in the biomedical field. These examples provide typical paradigms to fully realize the potential of DNA origami techniques by taking advantage of their unique programmability and addressability. This minireview summarizes the recent advancements of DNA origami techniques in biosensing, biocatalysis, and drug delivery, and the representative examples using DNA origami nanostructures for the spatial organization of functional molecules with nanometric precision are highlighted. We further discuss the possible limitations and challenges for in vivo applications, including stability issues and potential immunogenicity, and finally, propose some strategies to overcome these obstacles to fully realize the potential of DNA origami techniques in biomedical applications. © 2023 The Authors.

Covalent adaptable networks (CANs) enable reprocessability via dynamic bond exchange above their topology freezing transition temperature (T) despite chemical crosslinks. However, conventional CANs often exhibit insufficient viscosity reduction upon heating, necessitating extensive application of heat and pressure through direct contact for processing. In this study, a disulfide-bonded CAN is introduced to facilitate UV-assisted processing at room temperature, in addition to conventional thermal processing above T. At room temperature, UV irradiation accelerates stress relaxation, mirroring the effect of high-temperature activation (> T = 86 °C) without UV. Molecular dynamics (MD) simulation also reveals the underlying mechanism of UV- and heat-induced dynamic bond exchange. By incorporating magnetic NdFeB particles, magnetomechanical actuation of CAN/NdFeB microarrays is achieved. Unlike conventional approaches which rely on binders to maintain actuated shapes after removal of magnetic field, this system enables in-operando UV-fueled shape reconfiguration and fixation through dynamic bond exchange at room temperature, with reversible recovery of the original architectures on-demand. Furthermore, photoresponsivity allows for contactless spatiotemporal control over dynamic bond exchanges and resultant microarchitectures via a masking technique. This strategy offers facile, patternable 3D microfabrication and binder-free homologous shape-fixation in dry conditions without external pressure.

In this study, Nickel@Copper (Ni@Cu) bimetallic electrodes were fabricated via electrodeposition to assess their efficacy in electrochemical nitrate reduction (ENR). The Ni@Cu 3 m electrodes achieved a remarkable nitrate (NO 3 − ) reduction efficiency of 96.09 % and nitrogen selectivity of 96.08 % at a current density of 1.36 mA/cm² over an 8-hour reaction period. Extensive characterization techniques, including TEM, XPS, and XRD, were employed to analyze the structural and morphological features of the electrodes. Cyclic voltammetry was used to examine electron transfer interactions between surface nitrogen (N 2 ) species and copper foam electrodes, nitrate (NO 3 − ) reduction commenced within a potential range of −0.8 V to 0.1 V. The Ni loading on copper foam was optimized to enhance catalytic performance, and the effect of different pH levels on activity was systematically studied. The Ni@Cu 3 m electrodes demonstrated excellent long-term stability over 10 cycles, maintaining high efficiency and selectivity over multiple cycles. These results highlight the strong potential of bimetallic electrodes as efficient and reliable candidates for NO 3 − reduction in wastewater treatment applications.

Breast cancer is a disease in which cells in the breast mutate and turn malignant, where the mutated cells spread to other parts of the body and develop into secondary cancer. In 2018, there were 58,256 new cases of breast cancer. With improper handling, breast cancer can be lethal, where there are 22,692 deaths in 2018 alone. One type of cancer with the most sufferers is estrogen, progesterone, and glucocorticoid receptors. Research on cancer treatment continues by looking for potential substances as new drugs. Toxins from animals that are cytolytic can trigger apoptosis in cancer cells. Some studies suggest that the lethal factor of the stonefish poison, Stonustoxin (SNTX), has cytolytic properties that damage cell membranes. This study discusses the stonefish (Synanceia horrida) venom as a breast anticancer agent. Stonefish poison was milked using a syringe, and the SNTX purification was carried out by the FPLC method using a 5 ml HiTrap Q H.P. substantial anion column. The percentage of inhibition of MCF-7 breast cancer cells will be measured using the MTT Assay method. As a result, MCF-7 breast cancer cells could be inhibited with IC50 values of 8.2771 µg/ml.

Poly (hydroxybutyrate-co-valerate) (PHBV) was the ideal replacement for petroleum-based plastic, owing to its biocompatible, non-toxicity and naturally by bacteria. However, PHBV has high brittleness due to high crystallinity, becoming a major challenge for PHBV commercial production and limiting its use in molded products. Natural rubber (NR) and cellulose nanocrystal (CNC) created an excellent opportunity to enhance the modulus and minimize the effect of non-degradable materials utilized in the polymer matrix. This study demonstrates the formation of PHBV/NR/CNC ternary nanocomposites to obtain a commodity biomaterial with improved mechanical properties. The effects of CNC loadings (1, 3, 5 wt.%) on the mechanical properties and structure of the PHBV/NR/CNC nanocomposites were investigated. Based on the tensile test, the use of the CNC brought a more pronounced positive impact (especially 1wt.% CNC) to the PHBV/NR blend matrix, where it enhanced the tensile Young’s modulus of the PHBV/NR/CNC nanocomposites. Fourier transform infrared spectroscopy (FTIR) confirmed the success of peroxide crosslinking after the melt compounding process by using a heated two-roll mill.

Chiral phonons are concerted mirror-symmetric movements of atomic groups connected by covalent and intermolecular bonds. Finding chiral phonons in biocrystals is fundamentally and technologically important because these lattice vibrations should be highly specific to their short- and long-range organizations. Based on theoretical and experimental data they might be expected but not identified or utilized. Here we show that terahertz chiroptical spectroscopy enables registration and attribution of chiral phonons in microcrystals of numerous amino acids and dipeptides. Theoretical analysis and computer simulations confirm that sharp mirror-symmetric bands observed for left and right enantiomers originate from collective vibrations of biomolecules interconnected by hydrogen bonds into helical chains. Structure-property relationships for strong phonons with rotatory components in biocrystals were also identified. Bladder stones and health supplements display strong spectral signatures of chiral phonons indicating their immediate importance for biomedicine. © 2021, CC BY.
