Imprinted Photonic Hydrogels for the Size‐ and Shell‐Selective Recognition of Nanoparticles

Abstract: Sensors based on responsive photonic hydrogels have recently attracted considerable attention for visual medical diagnostics, pharmaceutical bioassays, and environmental monitoring. However, the use of these promising materials for the detection of nanoparticles (NPs) has never been explored so far, although the sensing of nanoobjects is a rapidly evolving area of research. To address this issue, we have combined the concepts of inverse-opal hydrogels and nanoparticle-imprinted polymers. In this way, we could … Show more

“…The structure of the grafted layer is a dense polymer brush [62, 63] with strong lateral stacking of PANI strands and packing defects where the molecular imprints are frozen. Such defects are similar to grain boundaries of polycrystalline materials, they allow for molecular imprints but would not be suitable for keeping the shape of large templates such a nanoparticles or proteins [64, 65] . A method that may be considered as being similar is building a self‐assembled monolayer (SAM) of fatty thiol molecules on a gold surface where the imprints are the “shadows” of the template molecules interacting with the gold surface, which leave holes inside the layer [66–68] .…”

“…Gam-Derouich et al used quantum dot (QD)-imprinted photo nic hydrogels for nanoparticle (NP) detection. [37] Nanoparticle detection can be quite useful in biosensing applications as it can be extended in identification of various biomolecules, enzymes, drugs, or other biomaterials. The cavities created on the poly methacrylic acid framework using the carboxy-functionalized CdTeSe quantum dots in the hydrogel allow for the shape and size selective sensing/identification of nanoparticles, which can be sensed by angle-resolved reflection spectroscopy.…”

“…Zinc ferrite has exhibited many special functional characteristics, such as, soft magnetism, [1] adjustable electrical conductivity and flue gas desulfurization, [2,3] due to its relatively stable chemical property, light corrosion resistant, non‐toxic and harmless for environment. Recently, non‐stoichiometric zinc ferrite has exhibited the excellent performances in the fields of industrial wastewater treatment, [4] wave absorption performance, [5] flame retardants, [6] photonics, [7] electrochemistry, [8,9] and catalysis, [10] compared with their bulk counterpart [11] . Different from ideal zinc ferrite with chemical formula of ZnFe 2 O 4 , the composition of non‐stoichiometric nanoparticles deviates from Fe/Zn=2, and may not conform to the rule of valence at first glance [12,13] .…”
