Lso developed a technique for preparing SAimmobilized redoxsensitive nanohydrogels via peptide
Lso created a technique for preparing SAimmobilized redoxsensitive nanohydrogels by means of peptide taginduced disulfide formation mediated by horseradish peroxidase (HRP) (Fig. a) . In this method, the peptides with sequences of HHHHHHC (Ctag) and GGGGY (Ytag) were genetically fused towards the N and Ctermini of SA (CSAY), respectively. Here, H, C, G and Y denote histidine, cystein, glycine and tyrosine, respectively. The CSAY was mixed with HRP and thiolfunctionalized arm PEG to yield a CSAYimmobilized hydrogel (CSAY gel) crosslinked with redoxsensitive disulfide bonds. The CSAY immobilized in the hydrogel retained its affinity for biotin, permitting the incorporation of any biotinylated functional biomolecules or synthetic chemicalFig. Schematic illustration of photolytic PAggs formation and lightinduced release of active proteins. a The chemical structure of BCR consisting of a biotinylated photocleavable protection group (red) and an aminoreactive group (black). b Schemes of PAggs formation. c Protein photoliberation from PAggs (Figure reproduced with permission fromRef Copyright with permission from John Wiley and Sons)Nagamune Nano Convergence :Web page of.

The speedy improvement of nanotechnology has resulted inside the successful synthesis and characterization of a variety of nanomaterials, creating them excellent candidates for signal generation and transduction in sensing. In other words, the one of a kind properties and functionalization of biomaterialconjugated nanostructures make them very useful for signal amplification in assays, other biomolecular recognition events and fabricating functional nanostructured biointerfaces Therefore
, nanomaterials and nanofabrication technologies play considerable roles in fabricating biosensors and biodevices (e.g colorimetric, fluorescent, electrochemical, surfaceenhanced Raman scattering, localized surface plasmon resonance, quartz crystal microbalance and magnetic resonance imaging (MRI)), like implantable devices for the detection of a broad selection of biomarkers with ultrahigh sensitivity and selectivity and speedy responses.
