Kefir grains offer numerous health benefits, including boosting the immune system, alleviating digestive issues, and enhancing antimicrobial activity. They are rich in beneficial probiotic bacteria that promote gut health and support a balanced intestinal microbiota. "Beta-lactoglobulin (β-lg), a well-known milk protein," is used to create nanofibril structures that can serve as scaffolds.

Lignin, traditionally considered a low-value byproduct of the pulp and paper industry, has gained significant attention in recent years as a sustainable precursor for the development of functional materials. This paradigm shift is driven by recent studies exploring the structure-property-performance relationships of lignin-based functional materials, which have provided valuable insights for selective chemical functionalization or pretreatment of lignin. Furthermore, the use of complementary analytical techniques has helped to shed light into lignin's complex and heterogeneous structure, opening new avenues for chemical modification.

Self-assembled DNA nanostructures have been popularly used to develop DNA-based electrochemical sensors by exploiting the nanoscale positioning capability of DNA origami. However, the impact of the electric field on the structural stability of the DNA origami framework and the activity of carried DNA probes remains to be explored. Herein, we employ DNA origami as structural frameworks for reversible DNA hybridization, and develop a single-molecule fluorescence imaging method to quantify electric field effects on DNA conformation and hybridization properties at the single-molecule level.

The development of sensors for monitoring breath acetone, a key biomarker for ketosis in diabetes mellitus, represents a critical frontier in medical diagnostics, promising a painless alternative to invasive blood tests. This review provides a comprehensive and critical evaluation of the state-of-the-art in acetone gas sensing technologies, including chemiresistive, optical, electrochemical, conductometric, and microwave platforms. We focus specifically on recent breakthroughs driven by advanced materials, analyzing how novel nanostructures from two-dimensional (2D) materials such as MXenes to porous metal-organic frameworks (MOFs) are engineered to push performance to clinically relevant parts-per-billion (ppb) sensitivity.

The development of therapeutic small interfering RNAs (siRNAs) has lately gained significant momentum due to their ability to silence genes in a highly specific manner. The main obstacle withholding the wider translation of siRNA-based drug modalities is their limited half-life and poor bioavailability, especially in extra-hepatic tissues. Consequently, various drug delivery systems (DDSs) have been developed to improve the delivery of siRNAs, including short delivery peptides called cell-penetrating peptides (CPPs).
