BACKGROUNDLipids and carbohydrates play essential functions in foods. In the last few decades, food scientists have studied the effects of carbohydrate‐lipid interaction on food's functional properties. However, how carbohydrate‐lipid complex‐derived materials affect the biological system is unknown. We created a myristic acid‐potato starch complex using a simple cooking approach. The complex was employed as a precursor for myristic acid‐potato starch complex‐based nanostructured materials (MPS‐NMs) fabrication through a liquid‐liquid extraction approach. A study was conducted on the structural and cytotoxic features of fabricated MPS‐NMs.RESULTSThe transmission electron microscopy images confirm spherical nanostructure formation with 3 ‐ 60 nm in size. After 24 h exposure, the chloroform fraction‐ and n‐hexane fraction‐based MPS‐NMs enhanced cell death by ~ 90% and ~ 82%, respectively. The chloroform fraction‐based MPS‐NMs (CMPS‐NMs) triggers apoptotic cell death in human mesenchymal stem cells (hMSCs). Also, n‐hexane fraction‐based MPS‐NMs (HMPS‐NMs) treated cells have red colour‐intact nuclei, attributed to necrotic cell death. CMPS‐NMs and HMPS‐NMs significantly decreased the mitochondria membrane potential and increased intracellular ROS levels. We observed significant downregulation in FMO, ATM and UGT gene expression levels in the exposed cells of CMPS‐NMs and HMPS‐ NMs. In addition, GSR and GSTA4 genes have upregulation in CMPS‐NMs and HMPS‐ NMs exposure.CONCLUSIONOur results conclude that the cooking process may lead to the formation of nanostructured material in food systems. These CMPS‐NMs and HMPS‐NMs may also contribute to cell metabolic disorders.This article is protected by copyright. All rights reserved.

Cadmium contamination is a severe threat to food safety. Therefore, the development of sensitive and selective cadmium detection strategies is urgently required. The elimination of background autofluorescence generated from the food matrix is critical to the optical assay for cadmium detection. Herein, a time-resolved phosphorescence sensor based on an “on-off” strategy was developed for cadmium determination in food samples. The phosphorescence nanoparticles were used as a luminous material to minimize the interference of background autofluorescence. The cadmium-binding aptamer was immobilized onto the magnetic beads and combined with a black hole quencher 1 (BHQ1) with complementary DNA as the target recognition element. With the presence of cadmium, the cadmium-binding aptamer bound to cadmium specifically and resulted in the release of BHQ1. The free BHQ1 remained in the solution after magnetic separation and quenched the phosphorescence. The phosphorescence intensity was negatively related to the concentration of cadmium. Under optimal conditions, the time-resolved phosphorescence sensor showed a linear response to cadmium concentration within a range from 0.05 to 5 ng mL−1 and with a detection limit of 0.04 ng mL−1. This “on-off” time-resolved phosphorescence sensor was successfully applied for cadmium detection in spring water and clam samples, which provided a rapid and straightforward method.

“…Nanoparticles are currently used in a wide and ever-increasing number of commercial, agricultural, medical, and research applications due to their usefulness in these areas; however, the biological effects of exposure to these NPs are not well understood. Nanoparticle exposure may also occur due to their presence as by-products in substances such as engine exhaust [ 1 , 2 ], cigarette smoke [ 3 ], electronic cigarette fluid and aerosols [ 4 , 5 ], cooked food [ 6 ], and various spray products [ 7 ]. The most detrimental exposure route for significant levels of NPs is through inhalation, a situation that can especially occur during workplace manufacturing, or through exposure to exhaust fumes or sprays [ 8 , 9 ].…”

Nanoparticles (NPs) are increasingly used in a wide variety of applications and products; however, NPs may affect stress response pathways and interact with proteins in biological systems. This review article will provide an overview of the beneficial and detrimental effects of NPs on stress response pathways with a focus on NP–protein interactions. Depending upon the particular NP, experimental model system, and dose and exposure conditions, the introduction of NPs may have either positive or negative effects. Cellular processes such as the development of oxidative stress, the initiation of the inflammatory response, mitochondrial function, detoxification, and alterations to signaling pathways are all affected by the introduction of NPs. In terms of tissue-specific effects, the local microenvironment can have a profound effect on whether an NP is beneficial or harmful to cells. Interactions of NPs with metal-binding proteins (zinc, copper, iron and calcium) affect both their structure and function. This review will provide insights into the current knowledge of protein-based nanotoxicology and closely examines the targets of specific NPs.
