In this perspective paper we argue for the fact that near infrared (NIR) technology, due to its unique properties, will become an indispensable green sensor technology in the future digitalized and sustainable food production. The future of near infrared spectroscopy (NIRS) in green analytics is bright. Ongoing advancements in NIR technology, coupled with increased accessibility and integration with advanced multivariate data analysis such as machine learning and artificial intelligence will further amplify the impact of NIRS across food, agricultural, environmental, and renewable energy domains. The miniaturization, increased portability, and enhanced affordability of NIR instruments, coupled with its integration into emerging technologies, will empower a diverse range of industries and researchers to address pressing global challenges with unprecedented precision and efficiency. The implementation of NIR technology in process analytical technology will enable the transition to future digitalized and sustainable food production. In a future circular economy, where waste streams, co-products and water are reclaimed and valorized, continuous measurements are necessary and in many cases, there are no sensor alternatives to NIR technology.

Near-infrared (NIR) triplet dyes are the cornerstones of cutting-edge biomedical and material applications. The difficulty in rational development of triplet dyes increases exponentially as the absorption wavelength shifts deeper into the NIR range. Although classical H-/J-typed packing of NIR dyes has the potential to enhance intersystem crossing (ISC) compared with that in single-chromophore dyes, the triplet state quantum yields remain limited in such strategy.

Near-infrared (NIR) spectroscopy analysis technology has become a widely utilized analytical tool in various fields due to its convenience and efficiency. However, with the promotion of instrument precision, the spectral dimension can now be expanded to include hundreds of dimensions. This expansion results in time-consuming modeling processes and a decrease in model performance.

Alveolar echinococcosis (AE) is a serious parasitic infectious disease that is highly invasive and destructive to the liver and has a high mortality rate. However, currently, there is no effective targeted imaging and treatment method for the precise detection and therapy of AE. We proposed a new two-step targeting strategy (TSTS) for AE based on poly(lactic--glycolic acid) (PLGA).

The development of intelligent nanotheranostic technology that integrates diagnostic and therapeutic functions holds great promise for personalized nanomedicine. However, most of the nanotheranostic agents exhibit "always-on" properties and do not involve an amplification step, which may largely limit imaging contrast and restrict therapeutic efficacy. Herein, we construct a novel nanotheranostic platform (Hemin/DHPs/PDA@CuS nanocomposite) by assembling DNA hairpin probes (DHPs) and hemin on the surface of PDA@CuS nanosheets that enables amplified fluorescence imaging and activatable chemodynamic therapy (CDT) of tumors.

A highly electron-rich S,N heteroacene building block is developed and condensed with FIC and Cl-IC acceptors to furnish CT-F and CT-Cl, which exhibit near-infrared (NIR) absorption beyond 1000 nm. The C-shaped CT-F and CT-Cl self-assemble into a highly ordered 3D intermolecular packing network via multiple π-π interactions in the single crystal structures. The CT-F-based organic photovoltaic (OPV) achieved an impressive efficiency of 14.
