Carbon nanotube (CNT) nanoporous membranes based on pre-aligned CNTs have superior nano-transportation properties in biological science. Herein, we report a smart temperature- and temperature-magnetic-responsive CNT nanoporous membrane (CNM) by grafting thermal-sensitive poly(N-isopropylacrylamide) (PNIPAM) and Fe3O4 nanoparticles (Fe3O4-NPs) on the open ends of pre-aligned CNTs with a diameter...

Cross-shaped-hole arrays (CSHAs) are selected for diminishing the polarization-dependent transmission differences of incident plane waves. We investigate the light transmission spectrum of the CSHAs in a thin gold film over a wide range of features. It is observed that two well-separated and high transmission efficiency peaks could be obtained by designing the parameters in the CSHAs for both p...

“Nano” is the prefix word originating from the Latin word ‘nanus’ meaning literally ‘dwarf’ and according to an International System of units (SI) it is used to indicate a reduction factor of 109 times. So nanosized materials are typically measured in terms of nanometers (1 nm is 10-9 m). Nanoscience can be defined as a study of the phenomenon and size reduction of materials at atomic or molecu...

The application of silicalite for improvement of working characteristics of conductometric enzyme biosensors for determination of sucrose was studied in this research. Biosensors based on different types of silicalite-modified electrodes were studied and compared according to their analytical characteristics. Polyethylenimine/glutaraldehyde/silicalite-modified biosensors showed higher sensitivi...

Breast cancer is the deadliest form of in women, but it also has very high survival rates when treated early. Existing breast detection methods such as mammography are ineffective early due to low uptake among women and need for regular screening. Therefore, biosensors have been proposed an alternative method cost-effective screening which may encourage more go regularly. In this paper, a gold ...

The analysis of (bio)available copper in complex environmental settings, including biological test media, is a challenging task. In this study, we demonstrated the potential of a recombinant Pseudomonas fluorescens-based biosensor for bioavailability analysis of CuSO4 and CuO nanoparticles (nano-CuO) in seventeen different ecotoxicological and microbiologial test media. In parallel, free Cu in ...
