In this paper, a highly sensitive graphene-based multiple-layer (BK7/Au/PtSe2/Graphene) coated surface plasmon resonance (SPR) biosensor is proposed for the rapid detection of the novel Coronavirus (COVID-19). The proposed sensor was modeled on the basis of the total internal reflection (TIR) techni...

In this article, a hybrid TiO2/Au/graphene layer-based surface plasmon resonance (SPR) sensor with improved sensitivity and capability for cancer detection is presented. The finite element method (FEM) was used for numerical analysis. The proposed SPR biosensor was structured based on the angular an...

In this paper, we have presented a design and simulation of a graphene-coated surface plasmon resonance (SPR) based biosensor for targeting specific biological components. We have explicitly shown the detection of the hemoglobin level in blood samples and the glucose concentration level in urine sam...

Gene silencing by RNA interference represents a promising therapeutic approach. The development of carriers, e.g., polymers, lipids, peptides, antibodies, aptamers, small molecules, exosome and red blood cells is crucial for the systemic delivery of siRNA. Cell-specific targeting ligands in the nano...

Black phosphorus quantum dots (BPQDs) have been prepared by a high turbulent shear rate generated from a household kitchen blender. A layer-by-layer disintegration mechanism of bulk BP crystals is suggested. As-synthesized BPQDs have shown excellent humidity sensing and photothermal converting prope...

p-Nitrophenol (p-NP) contaminants seriously endanger environmental and living beings health, hence to establish a sensitive and selective method is of great importance for the determination of p-NP. In this work, boron and nitrogen co-doped carbon dots (B,N-CDs) were synthesized by one-step hydrothe...

In this paper, two exclusive surface plasmon resonance (SPR) biosensors are proposed numerically utilizing the newly emerged transition metal dichalcogenides (e.g. PtSe2) composed with 2D materials (e.g. Graphene, MoS2 and WS2) onto the traditional SPR biosensors. The performance of the sensors is i...

Size‐dependent optical absorption of semiconductive (2H) layered molybdenum disulfide (MoS 2 ), exhibiting great discrimination abilities to single‐ and double‐stranded DNA (ssDNA) and (dsDNA), is studied. In the presence of high concentration of salt, layered MoS 2 trends to aggregate rapidly, lead...

Discovery of new antimicrobials is highly desired due to the emergence of microorganisms that have multi-drug resistant capability. The purpose of this study was to investigate the antimicrobial effect of dopamine (DA) on Escherichia coli. DA's inhibitory activity was tested at different initial E. ...

Aptamers are short non-coding, single-stranded oligonucleotides (RNA or DNA) developed through Systematic Evolution of Ligands by Exponential enrichment (SELEX) in vitro. Similar to antibodies, aptamers can bind to specific targets with high affinity, and are considered promising therapeutic agents ...

Ganz wenig genügt: Der Gehalt von Arsen in Brunnenwasser in Bangladesh sowie in käuflichem Trinkwasser und in Leitungswasser im US-Staat Mississippi kann mithilfe eines Assays auf der Basis dynamischer Lichtstreuung (DLS) angezeigt werden. Die hochempfindliche und selektive colorimetrische Analyse (...

Rapidly deployable sensor networks are portable, reusable, and can take advantage of a human user in the field attending to the deployment. Unfortunately, even small disruptions or problems in collected data must be addressed quickly, as the overall quantity of data gathered is small relative to lon...
