Trace detection of S. aureus cells in food samples via RCA-assisted SERS signal amplification with core-shell nanoprobe.

Staphylococcus aureus (S. aureus) has been identified as a indicator of food contamination. In this study, a sensitive and accurate biosensor strategy for S.

Nanogap-Assisted SERS/PCR Biosensor Coupled Machine Learning for the Direct Sensing of in Food.

() is the primary risk factor in food safety. Herein, a nanogap-assisted surface-enhanced Raman scattering/polymerase chain reaction (SERS/PCR) biosensor coupled with a machine-learning tool was developed for the direct and specific sensing of S. aureus in milk.

Application of odor imaging sensor coupled with hyperspectral imaging technology in monitoring the large yellow croaker (Larimichthys crocea) freshness.

Total volatile base nitrogen (TVB-N) is an important indicator for evaluating the freshness of aquatic products and holds great significance in assessing food safety. Traditional testing methods for TVB-N content use the Kjeldahl method, which has shortcomings like lengthy processes, cumbersome steps, and sample destruction. This study innovatively couples the hyperspectral imaging (HSI) technique with an odor imaging sensor (OIS) to achieve non-destructive prediction of TVB-N content in the large yellow croaker.

Cellulose nanofibril enhanced ionic conductive hydrogels with high stretchability, high toughness and self-adhesive ability for flexible strain sensors.

Preparation of ion-conductive hydrogels with excellent mechanics, good conductivity and adhesiveness is promising for flexible sensors, but remains a challenge. Here, we prepare a self-adhesive and ion-conductive hydrogel by introducing cellulose nanofibers (CNF) and ZnSO into a covalently-crosslinked poly (acrylamide-co-2-acrylamide-2-methyl propane sulfonic acid) (P(AM-co-AMPS)) network. Owing to the hydrogen bonding and metal coordination interactions among P(AM-co-AMPS) chains, CNF, and Zn, the resulting P(AM-co-AMPS)/CNF/ZnSO hydrogel exhibits high stretchability (1092 %), high toughness (244 kJ m), and skin-like elasticity (3.

Comparative assessment of vertical fracture resistance in endodontically treated roots with different obturating systems and techniques: a systematic review and network meta-analysis of in vitro studies.

Background: This study conducted a thorough assessment of vertical root fracture (VRF) resistance of endodontically treated teeth filled with various canal-filling systems and techniques through frequentist network meta-analysis (NMA).

Methods: A systematic literature search was performed to retrieve relevant publications using PubMed, Embase, ScienceDirect, Web of Science, and Cochrane Library databases. The retrieval time range was from Jan 2000 to Sep 2023.
