Biomaterials appear promising for creating wearable and electronic devices. For instance, natural silk is flexible, durable, comfortable, breathable and abundant. Silk can take many forms and adapt to the sought-out qualities of wearable devices. For sensor fabrication, silk’s amphophilic structure allows the facile adhesion of active materials. Moreover, substrates made of β-sheet crystallites offer outstanding mechanical strength. Here, we review synthesis and applications of modified silk in ...

Electrospun nanofibrous materials serve as potential solutions for several biomedical applications as they possess the ability of mimicking the extracellular matrix (ECM) of tissues. Herein, we report on the fabrication of novel nanostructured composite materials for potential use in biomedical applications that require a suitable environment for cellular viability. Anodized TiO2 nanotubes (TiO2 NTs) in powder form, with different concentrations, were incorporated as a filler material into a ble...

The use of titanium dioxide nanotubes in the powder form (TNTP) has been a hot topic for the past few decades in many applications. The high quality of the fabricated TNTP by various synthetic routes may meet the required threshold of performance in a plethora of fields such as drug delivery, sensors, supercapacitors, and photocatalytic applications. This review briefly discusses the synthesis techniques of TNTP, their use in various applications, and future perspectives to expand their use in m...

Abstract Significant enhancement in the performance of antibacterial bioactive materials in water purification has historically been achieved through the use of optimized nanostructured systems. This report demonstrates the dependance of the antibacterial performance of Titania on its morphology and the method of synthesis for the application of water microbial purification. In this regard, TiO2 with different morphologies, including nanoparticles (NPs), nanofibers (NFs) and nanotubes (NTs), wer...

Abstract A strategy for trace-level carbon-based electrochemical sensors is investigated via exploring the interesting properties of BaNb2O6 nanofibers (NFs). Utilizing adsorptive stripping square wave voltammetry (ASSWV), an electrochemical sensing platform was developed based on BaNb2O6 nanofibers-modified carbon paste electrode (CPE) for the sensitive detection of lornoxicam (LOR). Different techniques were used to characterize the fabricated BaNb2O6 perovskite NFs. The obtained data show the...
