“…NPs have emerged as feasible candidates for the development as therapeutic carriers due to their size, potential for loading drugs as well as controlling subsequent drug release . However, NP development has not succeeded in advancing some other desirable features for precise tagging of carriers with cell‐specific ligands to improve specificity or increase cellular and nuclear penetration via nonlysosomal routes.…”

DNA self‐assembly has proven to be a highly versatile tool for engineering complex and dynamic biocompatible nanostructures from the bottom up with a wide range of potential bioapplications currently being pursued. Primary among these is healthcare, with the goal of developing diagnostic, imaging, and drug delivery devices along with combinatorial theranostic devices. The path to understanding a role for DNA nanotechnology in biomedical sciences is being approached carefully and systematically, starting from analyzing the stability and immune‐stimulatory properties of DNA nanostructures in physiological conditions, to estimating their accessibility and application inside cellular and model animal systems. Much remains to be uncovered but the field continues to show promising results toward developing useful biomedical devices. This review discusses some aspects of DNA nanotechnology that makes it a favorable ingredient for creating nanoscale research and biomedical devices and looks at experiments undertaken to determine its stability in vivo. This is presented in conjugation with examples of state‐of‐the‐art developments in biomolecular sensing, imaging, and drug delivery. Finally, some of the major challenges that warrant the attention of the scientific community are highlighted, in order to advance the field into clinically relevant applications.

“…Additionally, researchers extended this concept using different enzymes and/or organic molecules to form organic-inorganic nanoflowers with greatly enhanced catalytic activities and stabilities in oxidation reactions. [30][31][32][33][34][35] Inspired by this literature, we have previously reported a novel HRP-Cu 2+ hybrid nanoflowers (hCu-NFs) containing HRP enzyme and Cu 2+ ions. 8 HRP enzyme is used as an organic component and Cu 2+…”

Catalytic activity and stability of HRP‐Cu2+ hybrid nanoflowers (hCu‐NFs) in the polymerization reactions of phenol derivatives was investigated. It was observed that the catalytic activity and stability of hybrid nanoflowers on the polymerization of the phenol derivatives was considerably higher compared to free Horseradish peroxidase (HRP) enzyme. The hCu‐NFs effectively polymerized phenolic compounds as a novel nanobiocatalyst and led to polymers having quite high yields, molecular weights, and thermal stabilities compared to free HRP enzyme. The hCu‐NFs provide substantial repeated use and showed some degree of catalytic activity even after fourth cycle experiment in the polymerization reactions.

“…In addition to that, very recent development proved that not only Cu-N bond but also Cu-O bond can be driving forces in the FHN formation [56][57][58] antimicrobial and antiparasitic properties [58,59]. Interesting results were obained that while the green tea (GT) extract (extracted in ethanol) and catechin produce the FHNs with very similar morpholoy, green tea (GT) extract (extracted in water) and caffeine based the FHNs have also quite similar shape an size.…”

A recent breakthrough in preparation of immobilized enzyme based biocatalysts achieving highly enhanced enzymatic activities and stabilities has become a great alternative to conventional immobilization techniques. The functional hybrid nanobiocatalysts (FHNs) fabricated in this immobilization composed of organic components (amino acid, peptide, protein, enzyme and plant extract) and inorganic components (various metal ions) give flowerlike morphology with narrow size distribution and porous structure. The enzyme incorporated FHNs exhibite greatly enhanced catalytic activities and stabilities compared to free and conventionally immobilized enzymes under various experimental conditions. In addition to that, the FHNs consisting of other organic components act as Fenton-like reagents and show peroxidase-like activity owing to presence of metal ions and porous structure in the FHNs. This report basically focuses on preparation, characterization, and bioanalytical applications of the FHNs and explain mechanism of the FHNs formation and thier enhanced activities and stabilities.Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted:
