“…As expect, no redox peak was observed at the curve a, b and c while a pair of well-dened redox peaks were observed at the curve e, indicating that the redox peak was attributed to the GOx. 10 The reaction mechanism of GOx on an electrode without the interference of oxygen was previously proposed, 34 and the equation was shown below:…”

Herein, we report the first example of using the Al-based porous coordination polymers (Al-PCP) as a template for preparation of nanoporous carbon through a two-step carbonized method. By applying the appropriate carbonized temperature in the first-step carbonization process, both high surface area and large pore volume are realized in the second-step carbonization process even at a hightemperature. The SEM images show that the carbonized Al-PCP before and after HF treatment (PCP) retained mostly crystallite shapes and sponge-like surface morphology. The TEM images of carbonized Al-PCP and PCP clearly exhibited high porosity with a wide range of pore sizes spanning from micro-to macropores. The maximum BET surface area and pore volume were 2773.5 m 2 g À1 and 1.885 cm 3 g À1 , respectively. The obtained highly nanoporous carbon PCPs were used to modify a glassy carbon electrode (GCE) based on glucose oxidase (GOx), resulting in efficient direct electron transfer and excellent bio-catalytic performance. In addition, a glucose/O 2 fuel cell constructed using Nafion/GOx/ PCP/GCE as the anode and an E-TEK Pt/C modified GCE as the cathode generated a maximum power density of 0.548 mW cm À2 at 0.41 V. The findings in this work may be helpful for exploiting novel nanoporous carbons derived from metal-organic framework (MOF) by using a two-step carbonization method for the immobilization of enzymes in enzymatic biofuel cells or biosensors.

“…the heterogeneous electron transfer rate constant (k s ) of GOD at PANI-TNTs|[Demim]Br|Nafion|GOD|GCE was estimated to be 9.3 s −1 at 100 mV s −1 (˛ is charge transfer coefficient, n, R, T and F have their usual electrochemical meaning), which is superior to 3.5 s −1 at a TiO 2 -coated carbon nanotube modified biosensor [32], 4.8 s −1 at a graphene modified biosensor [33] and 0.262 s −1 at a biosensor based on gold nanoparticles modified TiO 2 nanotube arrays [34]. The above results suggested that the DET of GOD had been significantly improved on PANI-TNT composite modified electrodes compared to that on the other nano-materials modified electrodes.…”

“…Instead, Bareket et al (2010) report the development of an electrochemical biosensor based on carbon nanotubes for detection of formaldehyde released from a cancer cell line treated with formaldehyde-releasing anticancer prodrugs [see Yang et al (2012) for pancreatic cancer]. In addition, Tasviri et al (2011) show an interesting application for diagnosis and therapy of diabetics: carbon nanotubes coated with amine-functionalised TiO 2 were used for glucose oxidase absorption in a novel biosensor for glucose determination.…”

Abstract:The purpose of this paper is to measure and analyse the rate of scientific and technological advance of some emerging nanotechnological research fields in biomedicine to detect path-breaking technological trajectories. The approach, based on exponential models of growth, shows the current evolutionary trends of nano-research that may underpin future patterns of technological innovation in biomedicine and nanomedicine. In particular, results show that biosensors, quantum dots, carbon nanotubes and nanomicelles have innovative applications in diagnostics and targeted therapies for cancers that have been generating a revolution in clinical practice. The present study also detects two main determinants that have been supporting continuous diffusion of nano-technology in biomedicine: convergence of genetics, genomics and nanotechnology and multiplicity of learning processes in clinical research/practice. These drivers have been paving groundbreaking pathways in biomedicine that can lead to longer, better and healthier living of societies in not-too-distant future.
