“…In contrast, by implementing non-covalent functionalization methods including electrostatic interactions, hydrogen bonding, van der Waals forces, and π–π interactions with polycyclic aromatic molecules that have been extensively applied to carbon allotropes such as graphene, the essential properties would be retained. Regarding the most popular aromatic structures, molecules with pyrene, pentacene, dopamine, benzopyrene, and 1-pyrenebutyrate could be named. − Because the effectiveness of non-covalent functionalization especially on bioelectronics devices has already been proven, we used 1-pyrene butyric acid (PBA) as a linker molecule with the aim of keeping the extraordinary electrical activity of GDY and also maintaining the simplicity of the procedure.…”

Graphdiyne's (GDY's) outstanding features have made it a novel 2D nanomaterial and a great candidate for electronic gadgets and optoelectronic devices, and it has opened new opportunities for the development of highly sensitive electronic and optical detection methods as well. Here, we testified a non-covalent grafting strategy in which GDY serves as a charge carrier layer and a bioaffinity substrate to immobilize biological receptors on GDY-based field-effect transistor (FET) devices. Firm non-covalent anchoring of biological molecules via pyrene groups and electrostatic interactions in addition to preserved electrical properties of GDY endows it with features of an ultrasensitive and stable detection mechanism. With emerging new forms and extending the subtypes of the already existing fatal diseases, genetic and biological knowledge demands more details. In this regard, we constructed simple yet efficient platforms using GDY-based FET devices in order to detect different kinds of biological molecules that threaten human health. The resulted data showed that the proposed non-covalent bioaffinity assays in GDY-based FET devices could be considered reliable strategies for novel label-free biosensing platforms, which still reach a high on/off ratio of over 10 4 . The limits of detection of the FET devices to detect DNA strands, the CA19-9 antigen, microRNA-155, the CA15-3 antigen, and the COVID-19 antigen were 0.2 aM, 0.04 pU mL −1 , 0.11 aM, 0.043 pU mL −1 , and 0.003 fg mL −1 , respectively, in the linear ranges of 1 aM to 1 pM, 1 pU mL −1 to 0.1 μU mL −1 , 1 aM to 1 pM, 1 pU mL −1 to 10 μU mL −1 , and 1 fg mL −1 to 10 ng mL −1 , respectively. Finally, the extraordinary performance of these label-free FET biosensors with low detection limits, high sensitivity and selectivity, capable of being miniaturized, and implantability for in vivo analysis makes them a great candidate in disease diagnostics and pointof-care testing.

“…This complex was used for catalyzing the hydrogenation of nitrobenzene to aniline, using 2-propanol as the transfer hydrogen source (Scheme 6). In that case also, the dendron onto the cobalt NPs could be recovered using a magnet and reused at least seven times [67]. The efficiency of magnetic nanoparticles as versatile supports for catalysts has been reviewed [68].…”

This review presents the state of the art of interactions between two different families of nanoobjects: nanoparticles—mainly metal nanoparticles, and dendrimers—mainly phosphorhydrazone dendrimers (or dendrons). The review firstly presents the encapsulation/protection of existing nanoparticles (organic or metallic) by phosphorus-based dendrimers and dendrons. In the second part, several methods for the synthesis of metal nanoparticles, thanks to the dendrimer that acts as a template, are presented. The properties of the associations between dendrimers and nanoparticles are emphasized throughout the review. These properties mainly concern the elaboration of diverse types of hybrid materials, some of them being used as sensitive chemosensors or biosensors. Several examples concerning catalysis are also given, displaying in particular the efficient recovery and reuse of the catalytic entities.

“…Both were used in catalyzed nitroarene transfer hydrogenation from 2-propanol. Recycling and recovery of the catalysts-Co NP with a magnet could be carried out seven times with still 100% yield in the eighth experiment with the dendritic catalyst, but not with the monomeric catalyst, which could be efficiently reused only four times [ 35 ].…”

AB5 Derivatives of Cyclotriphosphazene for the Synthesis of Dendrons and Their Applications

AB5 compounds issued from the reactivity of hexachlorocyclotriphosphazene are relatively easy to obtain using two ways: either first the reaction of one chloride with one reagent, followed by the reaction of the five remaining Cl with another reagent, or first the reaction of five chlorides with one reagent, followed by the reaction of the single remaining Cl with another reagent. This particular property led to the use of such compounds as core for the synthesis of dendrons (dendritic wedges), using the five functions for growing the dendritic branches. The single function can be used for the synthesis of diverse types of dendrimers (onion peel, dumbbell-shape, Janus), for covalent or non-covalent grafting to solid surfaces, providing nanomaterials, for grafting a fluorophore, especially for studying biological mechanisms, or for self-associations to get micelles. All these properties are reviewed in this paper.
