Since evaluating CA 19-9 antigen level in human serum is crucial for the early diagnosis of a vast range of diseases, especially pancreatic cancer, applying a simple, rapid, and sensitive detection method is essential. We employed an electrolyte-gated field-effect transistor with MoS2 nanosheets channel as an immunosensor to recognize CA 19-9 tumor...

Early detection of breast cancer, the first main cause of death in women, with robust assay platforms using appropriate biomarkers is of great importance for diagnosis and follow-up of the disease progression. This paper introduces an extra selective and sensitive label-free aptasensor for the screening of BRCA1 gene biomarker by taking advantage o...

Measuring CA 19-9 antigen level is critical for early diagnosis of pancreatic cancer, monitoring the treatment process, and predicting disease recurrence. The purpose of this research is to assess the application of novel few-layered TiS3 nanoribbons material as a channel material in electrolyte-gated field-effect transistor immunosensor for rapid...

Background: Since the evaluation of CA 19-9 antigen level in human serum is crucial for the early diagnosis of a vast range of diseases, especially pancreatic cancer, it is important to apply a simple, rapid and sensitive detection method. We employed an electrolyte-gated field-effect transistor with MoS2 nanosheets channel as an immunosensor for r...

Unique electronic, optical and mechanical properties of molybdenum disulfide (MoS2) hold great potential and can be harnessed as a key component in novel applications in electronics, optoelectronics, high-performance sensing material, and photodetection. Carbon quantum dots (CDs) have attracted a great deal of attention because of their biocompatib...

Sensitive, selective and inexpensive human immunodeficiency virus (HIV) diagnostics are urgently needed for early diagnosis and monitoring of the HIV. We developed a novel label free liquid-ion gated field-effect transistor (FET)-type biosensor for HIV-1 gene detection with the development of p-type semiconducting nickel oxide (NiO) thin film. Init...

MicroRNAs (miRNAs), critical biomarkers of acute and chronic diseases, play key regulatory roles in many biological processes. As a result, robust assay platforms to enable an accurate and efficient detection of low-level miRNAs in complex biological samples are of great significance. In this work, a label-free and direct hybridization assay using...

The development of a novel flexible and ultrasensitive aptasensor based on carboxylated multiwalled carbon nanotubes (MWCNTs)/ reduced graphene oxide-based field effect transistor (FET) has been reported for label-free detection of the ovarian cancer antigen (CA125). The fabricated sensor has a straightforward design based on the noncovalent attach...

The radio frequency sputtered nickel oxide thin film nanostructure deposited on glass substrate was used as a potential matrix for the realization of highly sensitive and selective field effect transistor-type lactate biosensor. Firstly, NiO-FET was tested for NADH detection showing a linear concentration range 1aM-1nM and a low detection limit of...

In this study, manganese oxide nanoparticles/reduced graphene oxide(MnOxNPs/rGO) was used as support for strong immobilization of flavin adenine dinucleotide(FAD). A thin film of rGO cast on the electrode surface, followed by performing electrodeposition of MnOxNPs at applied constant potential of +1.4 V vs. Ag/AgCl for 200 s. Finally, FAD was elec...

In this research a nanocomposite containing chitosan (Chit) and maltiwalled carbon nanotubes (MWCNTs) was applied as platform for immobilization of electrodeposited manganese oxide (MnOx) nanostructures. First, glassy carbon (GC) electrode modified with thin film of Chitosan/MWCNTs nanocomposite. Then MnOx nanostructures was electrodeposited onto C...

The graphene nanosheets/manganese oxide nanoparticles modified glassy carbon electrode (GC/GNSs/MnOx) was simply prepared by casting a thin film of GNSs on the GC electrode surface, followed by performing electrodeposi-tion of MnOx at applied constant potential. The GC/GNSs/MnOx modified electrode shows high catalytic activity toward oxidation of l...

In this study, the preparation of a glassy carbon (GC) electrode modified with chitosan/NH2-ionic liquid/manganese oxide nanoparticles (Chit/NH2-IL/MnOx) was described for electrocatalytic detection of theophylline (TP). First, chitosan hydrogel (Chit) was electrodeposited on the GC electrode surface at a constant potential (−1.5 V) in acidic solut...
