Metal halide perovskite quantum dots (MHP QDs), as a kind of fluorescent material, have attracted much attention due to their excellent photoluminescence (PL) yield (QY), narrow full width at half maximum (FWHM), broad absorption, and tunable emission wavelength. However, the instability biological incompatibility MHP QDs greatly hinder application in field biomedicine. Hydrogels are three-dimensional polymer networks that widely used biomedicine because high transparency biocompatibility. This review not only introduces latest research progress improving mechanical optical properties hydrogels/MHP but also combines it with existing methods for enhancing stability hydrogels, aiming provide new ideas researchers material selection constructing QD-embedded hydrogels. Finally, prospects future challenges introduced.

Cyclodextrin (CD)–hydrogel hybrids have emerged as versatile and multifunctional drug delivery systems, offering enhanced solubility, controlled release, improved bioavailability. By combining the inclusion complexation properties of CDs with swelling retention capabilities hydrogels, these hybrid systems overcome key challenges in conventional formulations. This review explores CD composition, hydrogel polymer selection, fabrication techniques, release factors, real-world therapeutic applications. Additionally, latest advancements stimuli-responsive nanogels, microneedle-based are discussed. While CD–hydrogel demonstrate significant potential, scalability, regulatory hurdles, clinical translation remain challenges. Future research should focus on smart loading strategies, validation to bridge gap between laboratory innovations commercial

Accurate wellbore positioning and control of the directional drilling trajectory allow collision avoidance proper target hitting [1]. Basic measurements while drilling, logging in-hole gyroscope surveys, drill-pipe depth measurements, other methods provide data regarding well positioning, but with a degree error uncertainty. real-time monitoring geological interpretation significantly improve geosteering to keep in production zone becomes extremely essential [2]. Determining origin drill cuttings high precision during propagation is critical challenge optimize placement, efficiency, detect oil-bearing formations maximize hydrocarbon recovery. To achieve this goal, it has been proposed use tracer materials that are periodically injected into at programmed intervals could mark formation bit site according depth. The hydrodynamic circulation mud wellhead would carry tagged flow shale shakers, hydrocyclone systems sampler, where pieces be separated analyzed without contamination fluid. Our study focuses on design development fluorescent tags can detected by UV light camera or hyperspectral optical devices combined image recognition engineering lab setup for workflow. Fluorescent designed as polymer matrix impregnated various fluorophores different emission wavelengths, which adhere when capsules bearing these crushed over bit.

The advancement of tissue engineering (TE) is driven by the development scaffolds that mimic mechanical, spatial, and biological environment extracellular matrix (ECM), crucial for regulating cell behavior repair. Hydrogels, 3D networks polymer chains, are particularly suited TE due to their high biocompatibility, ability water content, facilitate migration, sustain growth factor release, offer controllable physical properties. However, hydrogels mimicking ECM often face challenges related adhesion absence specific receptors. This issue can be addressed incorporating components into matrix, such as peptide sequence arginine-glycine-aspartic acid (RGD), known its role in adhesion. Additionally, carbon nanomaterials (CNMs) unique physicochemical properties improve scaffold-cell interactions. Despite potential benefits, there limited reports on combination. RGD-CNM enable a more accurate emulation natural cellular environment, enhancing applications. hybrid approach may promote robust along with exceptional mechanical electrical review outlines benefits these synergistic potential, aiming inspire new research directions this innovative field.
