The effectiveness and utility of near-infrared spectrophotometry for a rapid determination of nutrients in foods

, 2017
We examined the effectiveness of near-infrared spectrophotometry for the nutrient analysis of foods. The energy contents of 18 commercial confectionery products measured by near-infrared spectrophotometry were highly correlated with the values printed on

Mechanistic Design of Graphdiyne‐Based Multimodal Sensing Integrating Machine Learning and Photothermal Dynamics for Precision Recognition and On‐Demand Inactivation

Advanced Science, EarlyView.
A triple‐mode theranostic platform enables integrated electrochemical, colorimetric, and photothermal detection of bacterial infection. Glucose oxidation triggers H2O2 generation and TMB oxidation to oxTMB, producing color and thermal signals under 808 nm NIR irradiation.

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

Advanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.

Lighting up Macrophage Reprogramming Assists Immunosuppressive Niche Modulation in Primary Tumors and Tumor‐Draining Lymph Nodes of Breast Cancer

Advanced Science, EarlyView.
This study develops an intelligent NIR‐II‐responsive nanoplatform to combat immunosuppression in breast cancer. It enables real‐time visualization of macrophage activity via “off‐on” fluorescence while simultaneously reprogramming macrophages through the CSF‐1R and CD47‐SIRPα pathways.

Assessing variability of literature based methane indicator traits in a large dairy cow population

Biotechnologie, Agronomie, Société et Environnement, 2015
Description of the subject. Dairy production is identified as a major source of methane (CH4) emissions. Selective breeding represents one method for mitigating CH4 emissions but practical and cheap ways to measure this trait are not currently available.
