Electrospun Nanofibers including Organic/Inorganic Nanohybrids: Polystyrene- and Clay-Based Architectures in Immunosensor Preparation for Serum Amyloid A.

Diagnostic techniques based on biomolecules have application potential that can be realized in many fields, such as disease diagnosis, bioprocess imaging, food/beverage industries, and environmental pollutant imaging. Successful surface immobilization of biomolecules is critical to increasing the stabilization, sensitivity, and selectivity of biomolecules used in bioassay systems. Nanofibers are good candidates for the immobilization of biomolecules owing to many advantages such as morphology and pore size.

Development of an Enzymatic Biosensor Using Glutamate Oxidase on Organic-Inorganic-Structured, Electrospun Nanofiber-Modified Electrodes for Monosodium Glutamate Detection.

Herein, dendrimer-modified montmorillonite (Mt)-decorated poly-Ɛ-caprolactone (PCL) and chitosan (CHIT)-based nanofibers were prepared. Mt was modified with a poly(amidoamine) generation 1 (PAMAM) dendrimer, and the obtained PAMAM-Mt was incorporated into the PCL-CHIT nanofiber's structure. The PCL-CHIT/PAMAM-Mt nanofibers were conjugated with glutamate oxidase (GluO) to design a bio-based detection system for monosodium glutamate (MSG).

Biofunctionalization of PAMAM-montmorillonite decorated poly (Ɛ-caprolactone)-chitosan electrospun nanofibers for cell adhesion and electrochemical cytosensing.

The construction and biofunctionalization of the poly (Ɛ-caprolactone) (PCL)-chitosan (CHIT) nanofibrous mats, which included Polyamidoamine (PAMAM) dendrimer modified montmorillonite (Mt), for the cell adhesion and electrochemical cytosensing were accomplished in this report. After the intercalation of the PAMAM generation zero dendrimer into the Mt, PAMAM-Mt decorated PCL-CHIT electrospun nanofibers were formed. The addition of PAMAM caused the decrease of contact angle of PCL-CHIT nanofibers.
