#Review Two-Dimensional Material-Based Colorimetric Biosensors: A Review by Danzhu Zhu, Bin Liu and Gang Wei https://lnkd.in/e5j3g-fr MDPI Qingdao University #2Dmaterials #nanoparticles #nanozymes #hybridmaterials #colorimetricbiosensors #openaccess #Abstract Two-dimensional (2D) materials such as graphene, graphene oxide, transition metal oxide, MXene and others have shown high potential for the design and fabrication of various sensors and biosensors due to their 2D layered structure and unique properties. Compared to traditional fluorescent, electrochemical, and electrical biosensors, colorimetric biosensors exhibit several advantages including naked-eye determination, low cost, quick response, and easy fabrication. In this review, we present recent advances in the design, fabrication, and applications of 2D material-based high-performance colorimetric biosensors. Potential colorimetric sensing mechanisms and optimal material selection as well as sensor fabrication are introduced in brief. In addition, colorimetric biosensors based on different 2D materials such as graphene, transition metal dichalcogenide/oxide, MXenes, metal–organic frameworks, and metal nanoplates for the sensitive detection of DNA, proteins, viruses, small molecules, metallic ions, and others are presented and discussed in detail. This work will be helpful for readers to understand the knowledge of 2D material modification, nanozymes, and the synthesis of hybrid materials; meanwhile, it could be valuable to promote the design, fabrication, and applications of 2D material-based sensors and biosensors in quick bioanalysis and disease diagnostics.

I am excited to present my latest work entitled as "Flexible transparent conductors with a percolated Ag nanostructure and its application as efficient self-bias plasmonic photodetector."🌟🌟🌟 in prestigious Chemical Engineering Journal. This study focused on to produce plasmonic based transparent conductor. Here, we developed chemically implanted Ag-TiO2 thin film from a ion-conducting dielectric and then via physical vapor deposition (PVD) produce quite transparent conducting film over flexible substrate. Film's resistivity nearly ~50 Ω/□, with >70% transparency at 450 nm. However, transparency decreased to ~50% at 600 nm due to plasmon absorption of the film. So, film is further used for plasmonic hot electron based photodetectors, which shows a peak detectivity of 2.84 × 10¹² Jones at 510 nm and a fast response time of ~25 ms. I’m thankful to my collaborators and supervisor Dr. Bhola Nath Pal for their invaluable and continuous support. Further, i am looking forward for future discussions and collaborations in this exciting field if anyone is interested.

Are you looking to leverage nanomaterials to enhance your product? Due to the unique behaviors of nanomaterials, the design has a significant impact on a candidate material's ability to seamlessly integrate with your product. Cerion is known for the degree of customization and flexibility in its nanomaterial design processes for metal, metal oxide and ceramic nanoparticles. We take atoms and individual molecules, binding them together through precisely controlled chemical reactions, a process that enables us to build each nanoparticle from the ground-up. This has enabled our scientists to produce some of the smallest (down to 2 nm), monodispersed and non-agglomerated nanoparticles in the industry.

Pore size distribution plays a key role in the operation of many functional nanomaterials, such as membranes, sensors and electrodes. Our latest paper addresses challenges in characterizing 50-100nm pores with physisorption, often overlooked due to data reliability issues. Excited to share guidelines for enhanced methodology in thin film structures (<1 micron thickness) with non-destructive and rapid analysis.

All #nanomaterials are not made equal. If you are going to engage the world of #nanotechnology , your key performance target, is the quantum domain i.e., where size-induced quantum confinement effects emerge. Quantum confinement thresholds depend on the material composition but typically, occur well below 20 nm, for most nanomaterials. #Zinc Oxide (ZnO), a versatile material, may seem trivial in its bulk form but in its quantum-confined state, it comes with exceptional functionality. To design a quantum-phase #ZnO nanomaterial, it is essential to know the right specs to target. ZnO has a Bohr exciton radius of 2.34 nm, which implies that in order to generate sufficiently significant quantum confinement effects in ZnO, you need to operate with nanomaterial diameters of approximately 5 nm and below. Any nano-chemist who has worked with ZnO, understands that getting and keeping ZnO #nanoparticles that small, is no simple feat. Grinding micropowders, does not get you anywhere consistently close to that scale. Nanotechnology, in its true form, requires strategic nanomaterial design and bottom-up manufacturing processes. As a further measure, atomic lattice #engineering or #nanoarchitecture, become crucial, when high performance is desired, in a replicable manner. More importantly, ligands are best excluded from the synthesis process, if the quantum material is to perform at its best. #Quantum effects, are like a resonance feature, in a #nanomaterial. The closer you get to material-dependent quantum phase, the more enhanced its performance, the higher its surface area, the less of it you need in product dosage and last but not least, the more exciting new properties emerge. NANOARC's Atomically-Architectured, ligand-free ZnO #nanopowder, comes with the desired specs: NANOARCHITECTURE : ~ 5 nm spherical nanoparticles SURFACE AREA (BET) : 41530 m²/kg BAND GAP : ~ 3.5 eV COLOUR : White Nanopowder HEAT RESISTANCE : Up to 1975 °C (3587°F) APPLICATION SECTORS : Advanced #UV filtering, #Antibacterial, Antifouling, #Anticorrosion, antibiotic decontamination, #Electronics , #optics .

I am happy to share our last research work “Silk fibroin film decorated with ultralow FeCo content by sputtering deposition results in a flexible and robust biomaterial for magnetic actuation”. We created a magnetic hybrid material by coating a 6 μm-thick silk fibroin film with a 10 nm thick FeCo layer grown by magnetron sputtering deposition. Silk fibroin is a natural biopolymer with an optimal combination of biocompatibility and mechanical robustness while the FeCo alloy is the ferromagnetic material with the highest saturation magnetization. Sputtering deposition is an eco-friendly physical deposition technique, and allows to tailor size/shape/position of the area to be decorated. The hybrid material is biocompatible and water-resistant, flexible and robust. Even if that includes just a ultralow volume fraction (less than 0.1 vol %) of magnetic component, it exhibits a high bending response under magnetic actuation. The ultralow content of magnetic material reduces the risk of adverse health effects, thus paving the way for the use of the hybrid material also for bioactuation applications. This work was developed thanks to the collaboration of Lucia Del Bianco, Filippo Lanaro, Marco Coisson, Francesca Agostinacchio, Gabriele Greco, Nicola Pugno, and Antonella Motta.

I am thrilled to announce the publication of my latest article "Trade-off between high performance and long life due to nanofiller effects in polymer LEDs: MEH-PPV/Al2O3 nanocomposite study" in the Applied Surface Science journal. Our latest study delves into a crucial factor impacting the MEH-PPV polymer matrix within light-emitting diodes (PLEDs). Previous research uncovered the favorable impact of semiconducting nanoparticles on PLED efficiency. However, we aimed to discern whether this efficiency boost stemmed from the semiconductor properties of the nanofiller or the changes in the polymer matrix structure. Therefore, our study focuses on isolating these influences by utilizing non-conductive nanoparticles. Stay tuned as we unravel the intricate dynamics shaping PLED performance! A huge thanks to my colleagues and collaborators for their assistance. .........................................................................................................................
