High-toxicity secondary metabolites called aflatoxin are naturally produced by the fungus Aspergillus. In a warm, humid climate, Aspergillus growth can be considerably accelerated. The most dangerous chemical among all aflatoxins is B1 (AFB1), which has potential to cause cancer and several other health risks. As result, food forensicists now urgently need method that more precise, quick, practical for testing. current study focuses on development of highly sensitive, specific, label-free, rapid detection AFB1 using novel humanoid-shaped fiber optic WaveFlex biosensor (refers plasmon wave-based biosensor). probe been functionalized with nanomaterials (gold nanoparticles, graphene oxide multiwalled carbon nanotubes) anti-AFB1 antibodies enhance sensitivity specificity developed sensor. findings demonstrate sensor exhibits remarkable low limit 34.5 nM exceptional towards AFB1. Furthermore, demonstrated characteristics such as high stability, selectivity, reproducibility, reusability. These essential factors highlight significant proposed accurate in diverse agricultural samples.

Optical fiber probe based on LSPR for the detection of pesticide Thiram

Optics & Laser Technology, Год журнала: 2024, Номер 175, С. 110882 - 110882

Опубликована: Март 20, 2024

This article introduces an innovative sensor designed to explore the localized surface plasmon resonance (LSPR) effect using optical fiber technology for detection of pesticide Thiram. The proposed configuration consists etched silica multimode coated with gold nanoparticle (AuNP) layers able modulate reflected signal. What sets this apart is its ability stimulate LSPR modes single AuNPs, i.e. layer, and aggregation states nanoparticles or multilayer. capability has been demonstrated through both numerical simulations experimental results. Furthermore, device applied detect a specific pesticide, Thiram, serving as illustrative example chemical sensing, concentrations within 0.1–100 µM, achieving low limit (LOD) below 5 nM.

Nanomaterial-Based Repurposing of Macrophage Metabolism and Its Applications

Nano-Micro Letters, Год журнала: 2024, Номер 16(1)

Опубликована: Июль 15, 2024

Macrophage immunotherapy represents an emerging therapeutic approach aimed at modulating the immune response to alleviate disease symptoms. Nanomaterials (NMs) have been engineered monitor macrophage metabolism, enabling evaluation of progression and replication intricate physiological signal patterns. They achieve this either directly or by delivering regulatory signals, thereby mapping phenotype effector functions through metabolic repurposing customize fate for therapy. However, a comprehensive summary regarding NM-mediated visualization coordinated rewiring maintain phenotypic equilibrium is currently lacking. This review aims address gap outlining recent advancements in NM-based immunotherapy. We initially explore relationship between polarization, disease, before delving into NM innovations that visualize activity elucidate onset fine-tune its remodeling macrophage-centered Finally, we discuss prospects challenges immunotherapy, aiming accelerate clinical translation. anticipate will serve as valuable reference researchers seeking leverage novel intervention-matched immunomodulators macrophages other fields engineering.
