In the last fifteen years, the nucleic acid biosensors and delivery area has seen a breakthrough due to the interrelation between the recognition of nucleic acid's high specificity, the great sensitivity of electrochemical and optical transduction and the unprecedented opportunities imparted by nanotechnology. Advances in this area have demonstrated that the assembly of nanoscaled materials allows the performance enhancement, particularly in terms of sensitivity and response time, of functional nucleic acids' biosensing and delivery to a level suitable for the construction of point-of-care diagnostic tools. Consequently, this has propelled detection methods using nanomaterials to the vanguard of the biosensing and delivery research fields. This review overviews the striking advancement in functional nanomaterials' assisted biosensing and delivery of nucleic acids. We highlight the advantages demonstrated by selected well-known and rising star functional nanomaterials (metallic, magnetic and Janus nanomaterials) focusing on the literature produced in the past five years.

Drug therapy is an important measure to reduce the morbidity and mortality of influenza. However, small molecule drugs have inherent limitations, such as poor water solubility, non-specific biological distribution, and susceptibility to degradation during blood circulation, which impose a great burden on patients, both physically and mentally. Inspired by the high levels of reactive oxygen species (ROS) at the site of influenza A virus (IAV) infection, we have developed an intelligent responsive virus-mimicking nanodrug (Zana@HA-Lip) based on a biomimetic approach, reduces the damage of the drug to normal tissues or organs while achieving the purpose of antiviral therapy by precisely releasing the drug at the lesion site.

Significant advances in science and engineering often emerge at the intersections of disciplines. Nanoscience and nanotechnology are inherently interdisciplinary, uniting researchers from chemistry, physics, biology, medicine, materials science, and engineering. This convergence has fostered novel ways of thinking and enabled the development of materials, tools, and technologies that have transformed both basic and applied research, as well as how we address critical societal challenges.

Myocardial infarction (MI) is one of the leading causes of heart failure and death worldwide. While conventional treatments have limitations in promoting myocardial repair and regeneration, hydrogel, as a multifunctional biomaterial, shows great potential in MI treatment due to its unique physicochemical properties and biocompatibility. This paper reviews the multifunctional applications of hydrogels in MI therapeutics, including drug delivery (miRNAs, exosomes, ), electrical conduction, immunomodulation, detection, tissue engineering, and microfluidic functions.

Age-related Sarcopenia is a progressive, age-related disorder characterized by the loss of muscle strength, mass, and function, which is associated with an increased risk of falls and mortality and reduced quality of life, particularly in older adults. The pathophysiology of sarcopenia is complex, primarily driven by an imbalance between anabolic and catabolic muscle homeostasis. Effective interventions of sarcopenia is crucial to reverse or delay the progression of muscle disorder.

A key aspect of this reconfiguration is the interaction of DNA nanostructures with other biomolecules or chemical stimuli such as pH and ionic conditions. Sequence-based nanostructure reconfiguration is largely achieved by strand displacement which is based on single stranded toeholds.
