Three-dimensional (3D) printing technology provides a novel approach to material fabrication for various applications because of its ability create low-cost 3D printed platforms. In this study, printable graphene-based conductive filament was employed range electrodes (3DEs) using commercial printer. This simplistic and approach, which eliminates the need ex-situ modification post-treatment product. The nature 3DEs numerous deposition platforms electrochemical active nanomaterials such as...
We demonstrate refractive index sensors based on single mode tapered fiber and its application as a biosensor. utilize this optic biosensor, operating at 1550 nm, for the detection of protein (gelatin) concentration in water. The sensor is spectroscopy coupling core modes-fiber cladding modes excited by fundamental an optical when it transitions into regions from untapered regions. changes are determined wavelength shift transmission spectrum. proposed has sensitivity around 1500 nm/RIU...
Abstract In this work, sensitive detection of dengue virus type 2 E-proteins (DENV-2 E-proteins) was performed in the range 0.08 pM to 0.5 pM. The successful DENV at very low concentration is a matter concern for targeting early after onset symptoms. Here, we developed SPR sensor based on self-assembled monolayer/reduced graphene oxide-polyamidoamine dendrimer (SAM/NH rGO/PAMAM) thin film detect DENV-2 E-proteins. Surface characterizations involving X-ray diffraction (XRD) and...
Application of surface plasmon resonance (SPR) optical sensor in the diagnosis dengue virus (DENV) emerged over recent years. Immobilized monoclonal antibody (IgM) on gold/Fe-MPA-NCC-CTAB/EDC-NHS thin film was prepared using a spin coating technique. DENV E-protein can be detected by measuring SPR signal when IgM immobilized is exposed to solution, varying concentration ranging from 0.0001 nM 10 nM. A linear relationship between shift angle and up 0.01 nM, with sensitivity 39.96° nM−1 has...
The current research mainly focuses on transforming low-quality waste into value-added nanomaterials and investigating various ways of utilising them. hydrothermal preparation highly fluorescent N-doped carbon dots (N-CDs) was obtained from the carboxymethylcellulose (CMC) oil palm empty fruit bunches linear-structured polyethyleneimines (LPEI). Transmission electron microscopy (TEM) analysis showed that N-CDs had an average size 3.4 nm. were monodispersed in aqueous solution strongly under...
Dengue viral infection is one of the most common deadliest diseases and has become a recurrent issue for public health in tropical countries. Although spectrum clinical diagnosis treatment have recently been established, efficient rapid detection dengue virus (DENV) during viremia early febrile phase still great challenge. In this study, dithiobis (succinimidyl undecanoate, DSU)/amine-functionalized reduced graphene oxide-–polyamidoamine dendrimer (DSU/amine-functionalized rGO–PAMAM) thin...
We demonstrate a multiwavelength Brillouin-erbium fiber laser with double-Brillouin-frequency spacing. The wider channel spacing is realized by circulating the odd-order Stokes signals in Brillouin gain medium through four-port circulator. circulated are amplified and thus produce even-order at output. These then erbium block to form ring-cavity laser. Ten channels 0.174 nm that generated 0.5 mW pump power 150 1480 can be tuned from 1556 1564 nm. minimum optical signal-to-noise ratio of...
Abstract A versatile synthetic approach for development of highly fluorescent nitrogen-doped carbon dots (N-CDs) from carboxymethylcellulose in the presence linear polyethyleneimine (LPEI) has been developed. According to single factor method, central composite design incorporated with response surface methodology matrix was applied find and model optimal conditions temperature (220–260 °C), duration (1–3 h) LPEI weight (0.5–1.5%). The statistical results show that most significant parameter...
