“…[ 122 ] Second, the adsorption of ssDNA on MoS 2 could be released due to the photothermal effect of MoS 2 for potential responsive drug delivery and release ( Figure a). [ 123 ] Overall, 2D materials, working as desired platforms, could be used for the transportation and delivery of various genetic materials (Figure 10b,c). [ 124 ]…”

“…Nevertheless, the hybrid of DNA resulted in the separation of DNA and nanostructures, and consequently, the aggregation of layered nanostructures occurred. The discriminated performance caused by the aggregation promotes the fabrication of sensing protocols, and a series of objectives, such as target DNA, [ 33 ] small molecules, [ 123 ] and heavy metal ions could be detected. [ 29 ] Additionally, thiolated DNA was covalently modified on Au NPs, and target‐induced disassembly of aggregates was monitored by the extinction spectra.…”

Mendelian genetics spark the century‐old revolution in genetic engineering. DNA structural engineering may well spark a similar revolution in chemistry. The first few man‐made DNA structures are purely DNA but increased interest in hybrid DNA with other molecules is regaining popularity. Nucleic acids can interact with non‐nucleic acid‐based materials, showing their materialistic flexibility and potential and the prospect of forming new future materials. This review provides a deep materialistic background based on the interaction of nucleic acids with these non‐nucleic acid‐based materials covering comprehensive topics. The non‐nucleic acid materials are broadly divided into biological materials, for example, small‐biomolecules, peptides, proteins, and lipids, and non‐biological materials consisting of metal ions, chemical molecules, low‐dimensional nanomaterials, and micro‐scale polymers. Of significance, combining the unique properties of nucleic acids with these non‐genetic materials can bring about surprising synergistic characteristics and drive attractive applications in bio‐imaging, chem/bio‐sensing, disease therapies, antimicrobial works, and even information storage.

“…[10][11][12] In case of nonspecific aggregation, gold NPs are normally prepared in the presence of stabilizers, such as small molecules, 13 proteins, 14 nucleic acids, 15,16 polymers, 17 and inorganic materials, 18,19 and LSPR performances promote a broad range of applications. [20][21][22] Nevertheless, even though gold NPs can be stabilized by chemical ligands, slight changes in colorimetric signals are still recorded when nanoprobes are added in these complex samples. It is supposed that if gold NPs could be everlastingly encapsulated on a net substrate, the stability and reproducibility of their growth and sensing applications can be improved.…”

“…The analysis of the aqueous phase might be restricted due to the weak stability and anti-interference capacity of nanoprobes. In order to address those issues, the establishment of an in situ and real-time analysis method in non-aqueous systems is highly encouraged for the measurement of heavy metal ions. − …”

The hybrid of l-cysteine and agarose can reduce HAuCl4 and support the rapid growth of plasmonic gold nanoparticles (Au NPs) in the hydrogel phase. The l-cysteine-doped agarose hydrogel (C-AGH) not only offers the substrate the capacity to reduce Au(III) ions but also stabilizes and precisely modulates the in situ grown Au NPs with high repeatability, easy operation, and anti-interference performance. Herein, before the incubation of HAuCl4, the improved hydrogel is preincubated in the aqueous solution containing mercury ions, and the cysteine can specifically conjugate with mercury via the thiol groups. Subsequently, the responsive allochroic bands from dark blue to red can be identified in the solid hydrogel after the incubation of HAuCl4, which is attributed to the formation of regulated Au–Hg nanoamalgams. As a proof-of-concept, toxic Hg2+ ions are exploited as targets for constructing novel sensing assays based on the improved C-AGH protocol. Based on naked-eye recognition, Hg2+ could be rapidly and simply measured. Additionally, the high-throughput and trace analysis with a low limit of detection (3.7 nM) is performed using a microplate reader. On the basis of the filtering technique and remodeling of hydrogels, C-AGH working as the filtering membrane can even achieve the integration of enrichment and measurement with enhanced sensitivity. Significantly, the strategy of using an allochroic hydrogel with the staining of Au NPs can promote the rapid and primary assessment of water quality in environmental analysis.
