Abstract Carbon quantum dots (CQDs) have emerged as promising organic nanomaterials due to their unique physicochemical properties and versatile applications. In recent years, there has been a growing interest in exploring the role of CQDs improving performance construction building materials, including cement, concrete, asphalt. This paper presents comprehensive literature review articles focusing on synthesis methods graphene (GQDs), characteristics, effects mechanical, thermal, durability cement-based materials. Furthermore, potential challenges future research directions this field towards carbon capture, utilization, storage (CCUS) direction are also discussed. The mechanisms behind these improvements analyzed, interfacial bonding between CQDs, seeding nucleation cement hydration process, filling effect. Additionally, addresses associated with CQD implementation, such cost-effectiveness large-scale implementation. Finally, suggested outline for optimizing used materials many is discussed, suggesting novel ways high-performance, functional, sustainable smart Graphical

Surface-enhanced Raman scattering (SERS) is an advantageous method for organic chemical and biological sensing. Benzoic acid, benzisothiazolinone, thiram are common model compounds used to study the interaction of toxic substances with metal surfaces using SERS spectroscopy. Metal-organic frameworks, their high porosity large surface area, have recently received a lot attention in sensing applications. Plasmonic porous structures promising substrates because broadband charge-transfer resonance reproducibility fabrication. Furthermore, exceptional enhancement electromagnetic field makes plasmonic nanomaterials ideal substrates. In this study, we developed based on ZIF-8/Au NPs through self-assembly process that forms stacked layers. The substrate demonstrated remarkable ability enhance scattering, enabling ultrasensitive detection various target molecules at micromolar concentrations. These attributes establish it as biosensing
