Sustainable, Flexible, and Biocompatible Enhanced Piezoelectric Chitosan Thin Film for Compliant Piezosensors for Human Health

Gaia de Marzo et al.

Summary: Continuous and seamless monitoring of human health requires the development of compliant, comfortable, and safe wearables. The use of piezoelectric biopolymers in the form of thin films, such as chitosan, perfectly fulfills these requirements due to their flexibility, sensitivity, and biocompatibility. This study presents a simple method to significantly increase the piezoelectric coefficient of thin chitosan films and demonstrates their potential for fabricating biodegradable, transparent, thin, and flexible piezoelectric macro- and microtransducers, specifically ultrasound transducers.

Forster resonance energy transfer (FRET) between CdSe quantum dots and ABA phosphorus(V) corroles

Ritika Kubba et al.

Summary: In this study, highly fluorescent phosphorus(V) corrole was synthesized and combined with CdSe quantum dots to investigate the Foerster resonance energy transfer (FRET) mechanism between the CdSe quantum dots (donor) and phosphorus corrole (acceptor). The spectral overlap between the quantum dot's emission and the corrole's absorption was significant enough to result in FRET. UV-vis measurements showed increased absorption bands when phosphorus corrole was added to CdSe quantum dots, indicating QD-corrole conjugation. Both steady state and time-resolved fluorescence measurements confirmed quenching of CdSe QDs' fluorescence intensity and lifetime, suggesting FRET.

Chitosan-based nanoparticles against bacterial infections

Somaye Rashki et al.

Summary: Chitosan nanomaterials have gained attention in biomedicine for their high levels of biodegradability and biocompatibility, along with antimicrobial effects. Functional modification with other natural compounds, metallic antimicrobial particles, and antibiotics can enhance the efficiency of chitosan in wound dressing with antimicrobial activity. The antibacterial effect of chitosan is mainly associated with the leakage of intracellular content due to malfunction and altered permeability of the negatively charged cell membrane, on which chitosan is adsorbed. Additionally, chitosan nanoparticles possess favorable features of nanoparticles and their chitosan base, thereby exhibiting strengthened antibacterial potential. Polycations in chitosan nanoparticles target negatively charged bacterial membranes, resulting in a stronger effect on bacterial cells compared to pure chitosan.
