“…Its uses are not only limited to electrochemical sensors, also have been applied for biosensors applications, such as glucose, DNA and H 2 O 2 sensing. For instance, Pd nanoparticles modified GCE [9], Pd nanoparticles and glucose oxidase onto nafion-solubilized carbon nanotube electrodes for glucose sensing [10], Pd nanoparticles combined carbon nanotubes modified GCE for electrochemical DNA biosensors [11], Pd nanoparticles encapsulated channels for protein biosensing and the reduction of H 2 O 2 [12], conductive Pd nanoparticles nanocage for H 2 O 2 sensing [13], electro spun Pd nanoparticles-loaded carbon nanofibers for H 2 O 2 and NADH reduction [14] and DNAtemplated preparation of Pd nanoparticles on ITO for H 2 O 2 reduction and ascorbic acid (AA) oxidation [15] have been reported.…”

“…Coffer's group pioneered the synthesis of CdS nanowires using DNA, proving the possibility of NP synthesis via electrostatic‐interaction‐induced assembly. Later, various semiconductor nanowires (e.g., CdS and Fe 3 O 4 ) and metal nanoparticles/nanowires (e.g., gold, silver, palladium, platinum, cobalt, nickel, and copper) have been prepared via this method. The common process for nanowire synthesis in solution is as follows: cations first absorb onto the DNA backbone to form complexes due to electrostatic interactions.…”

In recent years, due to its unparalleled advantages, the biomimetic and bioinspired synthesis of nanomaterials/nanostructures has drawn increasing interest and attention. Generally, biomimetic synthesis can be conducted either by mimicking the functions of natural materials/structures or by mimicking the biological processes that organisms employ to produce substances or materials. Biomimetic synthesis is therefore divided here into "functional biomimetic synthesis" and "process biomimetic synthesis". Process biomimetic synthesis is the focus of this review. First, the above two terms are defined and their relationship is discussed. Next different levels of biological processes that can be used for process biomimetic synthesis are compiled. Then the current progress of process biomimetic synthesis is systematically summarized and reviewed from the following five perspectives: i) elementary biomimetic system via biomass templates, ii) high-level biomimetic system via soft/hard-combined films, iii) intelligent biomimetic systems via liquid membranes, iv) living-organism biomimetic systems, and v) macromolecular bioinspired systems. Moreover, for these five biomimetic systems, the synthesis procedures, basic principles, and relationships are discussed, and the challenges that are encountered and directions for further development are considered.

Electrochemical biosensors have a key importance in many areas including clinical, biological, pharmaceutical, forensic, environmental and agricultural applications. They have the advantages of rapid, easy and low cost preparation allowing the localization of biocompound on electrodes of any size with independence of sample turbidity, high sensitivity and high selectivity. Electrochemical devices have attracted considerable interest in the development of DNA hybridization biosensors. They rely on the conversion of hybridization event into a direct electrochemical signal. Many efforts have been carried out in the detection of DNA hybridization for improving the stability, reproducibility and sensitivity.This review summarizes the advanced electrochemical methodologies involved in nucleic acid hybridization performed by using polymer technology, nanoparticles (NPs), magnetic particles, and carbon nanotubes (CNTs). The preparation of polymer modified electrodes especially including conducting polymers and their applications for DNA hybridization are given with the advantages of electrocatalysis, good electroactivity, high sensitivity and providing suitable matrix for DNA immobilization. The role of various nanomaterials in biosensors with the advantages of high surface area, fast heterogeneous electron transfer, excellent biocompatibility and enhanced signal with a good selectivity are presented. The combination of these techniques is also discussed in details.
