Though the magnetoimpedance effect was discovered two decades ago, the biomedical applications of the magnetoimpedance sensor are still in their infancy. In this review, the authors summarized the magnetoimpedance effect in soft ferromagnetic wires, ribbons and thin films for biosensing applications. Recent progress and achievements of the magnetoimpedance-based biosensing applications including the detection of magnetic Ferrofluid, magnetic beads, magnetic nanoparticles, magnetically labeled bioanalytes and biomagnetic fields of living systems were reviewed. The modification effect of the biochemical liquids, agglomeration effect of the magnetic particles, and the effect of the stray magnetic field on magnetoimpedance were investigated in this review. Some constructive strategies were proposed for design of the high-performance magnetoimpedance biosensor, for quantitative and ultrasensitive detection of magnetically labeled biomolecules. The theoretical and experimental results suggest that the magnetoimpedance sensors are particularly suitable for highly sensitive detection of low-concentration biomolecules, and might be used for early diagnosis and screening of cancers.

Vitamins are indispensable active components of the human body, and their abnormal levels are often closely related to various diseases. Therefore, searching for ultra-sensitive and accurate vitamin detection strategies is essential and significant for clinical examination and diagnosis. In this paper, multi-wavelength emission fluorescent nitrogen-doped carbon dots (N-doped CDs) were synthesized by a one-step solvothermal method using four-leaf green fluorescent extract, O-phenylenediamine, and β-cyclodextrin as the raw materials, and N, N-dimethylformamide as the solvent.

Nanozymes, a class of nanomaterials mimicking natural enzymatic functions, have gained significant attention due to their exceptional biocatalytic properties and wide-ranging applications in biosensing. The total antioxidant capacity (TAC) can serve as a crucial parameter for assessing food quality, guiding dietary choices, and monitoring health conditions. In recent years, various nanomaterials with peroxidase (POD)-like and oxidase (OXD)-like activity have been widely used for TAC determination.

Multifunctional Prussian blue analogs (PBAs) have received extensive attention in the detection and degradation of food hazards. However, the development of new structural adjustment strategies to further improve their performance remains a huge challenge. Herein, the "interface recombination" post-processing approach was established to regulate the structure of PBAs using a microwave-assisted solvothermal method combined with acid etching.

In cuttings, detached leaves or stems are exposed to many stresses during the root regeneration process. Here, we show that the detached Arabidopsis thaliana leaf can tolerate mild osmotic stress and still regenerate roots. Under stress conditions, wounding and stress upregulate the jasmonate (JA) signaling pathway transcription factor gene MYC2 and the abscisic acid (ABA) signaling pathway transcription factor gene ABA INSENSITIVE5 (ABI5).

As promising noninvasive biomarkers, nucleic acids provide great potential to innovate cancer early detection methods and promote subsequent diagnosis to improve the survival rates of patient. Accurate, straightforward and sensitive detection of such nucleic acid-based cancer biomarkers in complex biological samples holds significant clinical importance. However, the low abundance creates huge challenges for their routine detection.
