Research related to the development and application of luminescent nanoparticles (LNPs) for chemical and biological analysis and imaging is flourishing. Novel materials and new applications continue to be reported after two decades of research. This review provides a comprehensive and heuristic overview of this field. It is targeted to both newcomers and experts who are interested in a critical assessment of LNP materials, their properties, strengths and weaknesses, and prospective applications. Numerous LNP materials are cataloged by fundamental descriptions of their chemical identities and physical morphology, quantitative photoluminescence (PL) properties, PL mechanisms, and surface chemistry. These materials include various semiconductor quantum dots, carbon nanotubes, graphene derivatives, carbon dots, nanodiamonds, luminescent metal nanoclusters, lanthanidedoped upconversion nanoparticles and downshifting nanoparticles, triplet−triplet annihilation nanoparticles, persistent-luminescence nanoparticles, conjugated polymer nanoparticles and semiconducting polymer dots, multi-nanoparticle assemblies, and doped and labeled nanoparticles, including but not limited to those based on polymers and silica. As an exercise in the critical assessment of LNP properties, these materials are ranked by several application-related functional criteria. Additional sections highlight recent examples of advances in chemical and biological analysis, point-of-care diagnostics, and cellular, tissue, and in vivo imaging and theranostics. These examples are drawn from the recent literature and organized by both LNP material and the particular properties that are leveraged to an advantage. Finally, a perspective on what comes next for the field is offered.

Supramolecular materials which do not require chemical reactions to form compositessuch as dye-zeolite composites/artificial antenna systems in zeolite channels, [25][26][27][28][29][30][31][32][33] biomolecules and chromophores immobilized in 1-D channels, [34][35][36][37][38][39][40][41] or low-dimensional nanoarchitectures of molecular clusters [42][43][44] -have been successfully realized.

Zeolites are known as scaffolds for the assembly of molecules via non-covalent interactions, yielding organized supramolecular materials. Yet their potential in driving the growth of low-dimensional systems requiring covalent bond formation is still uncharted. We incorporated 1,5-hexadiene in the channels of a high-silica mordenite and analyzed the material by infrared spectroscopy, X-Ray powder diffraction, thermogravimetric and modeling techniques. Thanks to the few zeolite acid sites, 1,5-hexadiene experiences a slow conversion to a polymer, mainly formed by cyclopentane units and featuring short side chains able to fit the channels. The shape-directing abilities of zeolite framework play a twofold role, involving first the organization of the monomers inside the void-space and then the linear growth of the chain, dictated by the channel geometry. These findings highlight the molding action of zeolites in directing transformations of covalent bonds under ambient conditions and may provide insights for obtaining confined polymers with intriguing perspective applications.

“…In this way, the confining environment of the pores could not only protect the guest molecules in hostile environments, but also favour the formation of organized supramolecular systems with technologically appealing collective properties [19]. This kind of strategy has been successfully applied to the encapsulation of molecules in crystalline microporous hosts, producing hybrid devices now actually exploited in solar energy harvesting [20,21,22,23,24] and theranostics [25,26,27,28]. On the other hand, the encapsulation of a macromolecular system, such as a protein, requires larger pores size, hence the need of mesoporous silica matrices [14,29].…”

Confining a Protein-Containing Water Nanodroplet inside Silica Nanochannels

Incorporation of biological systems in water nanodroplets has recently emerged as a new frontier to investigate structural changes of biomolecules, with perspective applications in ultra-fast drug delivery. We report on the molecular dynamics of the digestive protein Pepsin subjected to a double confinement. The double confinement stemmed from embedding the protein inside a water nanodroplet, which in turn was caged in a nanochannel mimicking the mesoporous silica SBA-15. The nano-bio-droplet, whose size fits with the pore diameter, behaved differently depending on the protonation state of the pore surface silanols. Neutral channel sections allowed for the droplet to flow, while deprotonated sections acted as anchoring piers for the droplet. Inside the droplet, the protein, not directly bonded to the surface, showed a behavior similar to that reported for bulk water solutions, indicating that double confinement should not alter its catalytic activity. Our results suggest that nanobiodroplets, recently fabricated in volatile environments, can be encapsulated and stored in mesoporous silicas.
