“…The emission quantum yield and the fluorescence lifetime values are lower than those of the free molecules. Intermolecular interactions such as hydrogen bonding or van der Waals forces between portions of the nanoparticles and the curcuminoid molecule can generate fluorescence deactivation, as observed in other silicon oxide nanoparticles mixed with fluorophores [ 56 ]. However, due to the covalent incorporation of a curcuminoid molecule, it was possible to transfer optical properties such as absorption and emission in the visible range to the nanoparticle, a property which it did not initially possess.…”

A new curcuminoid molecule (3) has been designed and synthesized, containing a central -(CH2)2-COOH chain at the α carbon of the keto-enol moiety in the structure. The carboxylic acid group is added to react with exposed amino groups on silica oxide nanoparticles (nSiO2), forming an amide bond to attach the curcuminoid moiety to the nSiO2 covalently. The Kaiser test quantifies the functionalization degree, yielding 222 μmol of curcuminoid per gram of nanoparticles. The synthesized hybrid nanosystem, nSiO2-NHCO-CCM, displays significant emission properties, with a maximum emission at 538 nm in dichloromethane, similar to curcuminoid 1 (without the central chain), which emits at 565 nm in the same solvent. Solvent-induced spectral effects on the absorption and emission bands of the new hybrid nanosystem are confirmed, similar to those observed for the free curcuminoid (1). The new nanosystem is evaluated in the presence of kerosene in water, showing an emission band at 525 nm as a detection response. The ability of nSiO2-NHCO-CCM to change its fluorescence when interacting with kerosene in water is notable, as it overcomes the limitation caused by the insolubility of free curcuminoid 1 in water, allowing for the exploitation of its properties when connected to the water-stable nanosystem for future detection studies.

“…78 In addition, recent studies provide insights into light coupling and transmission through the space, addressing different photo biological receptors in unicellular microorganism, probably developed from Bi-coloured FRET nano-emitters. 79 And this is based on the effect of energy levels and consequent properties by interaction with electromagnetic fields. The electromagnetic fields could be generated from the molecular scale to the nanoscale varying in nature and intensity, which could also reach the quantum level 80 .…”

In this communication the concept of functional materials is understood such as real modified substrates for nanomedicine applications. Functional and modified substrates focused on microcapsules and devices for new nanomedicine diagnosis and treatments. Cases of different materials are shown to support the functionality strategy, as in particular chemicals, pharmacophores, and controlled nano-chemistry for the design of nanoplatforms. Recent studies have reported hybrid inorganic/organic compositions for biocompatible, biodegradable, and support materials added to particular physical properties such as conductive, semiconductive, and high electromagnetic fields from the near field within the nanoscale to far-field applications and new nano-pharmacophores and nanomedicine therapeutics. New approaches are shown from the nano-scale to the micro- and higher sizes of substrates for improved therapeutic strategies. Micro-capsules for biosensing and drug delivery applications were developed. In addition, we report recent and novel research centered on implantable, portable, and wearable devices applied to future treatments.

“…10). 97 The effect mentioned was controlled by the incorporation of the proper laser dye emitters in silica nanoparticles and targeted laser excitation to light delivery and transference through the biomaterial. In this perspective, the proposed generation of new free labelling bioimaging approaches from modied substrates could also be mentioned.…”
