Abstract

Asylum seekers experience high levels of acculturative stress and identity disruption during the initial settlement phase, often overwhelming traditional, formal support systems. This research aimed to systematically investigate the dynamic role of mobile technology as a self-directed psychosocial resource that mediates psychological adaptation and facilitates identity negotiation. A quantitative, longitudinal study tracked 80 asylum seekers over a six-month period, utilizing Structural Equation Modeling (SEM) to analyze digital trace data collected via the custom Digital Identity and Adaptation Index (DIAAI), alongside validated psychological scales (ASAS, COPE). Results confirmed a strong inverse relationship (beta = -0.45) between Host-Country Media Consumption and Acculturative Stress, validating information seeking as a primary coping mechanism. Furthermore, the findings demonstrated a successful pattern of bi-cultural identity negotiation, where active digital engagement with both the origin and host cultures simultaneously facilitated stress reduction and preserved cultural integrity. The study concludes that the mobile device is a crucial self-directed psychosocial resilience tool, challenging linear models of acculturation. This evidence-based framework justifies the integration of targeted mobile applications into humanitarian aid programs to enhance long-term psychological and integration outcomes.

Abstract

Cancer metastasis is the primary cause of cancer-related mortality, yet its dynamic progression in living systems remains difficult to visualize due to limitations of existing imaging probes. Conventional fluorescent dyes used for in vivo bioimaging often suffer from poor photostability, limited brightness, and insufficient tissue penetration, restricting their ability to capture metastatic events in real time. This study aims to develop and evaluate near-infrared-emitting quantum dots as fluorescent probes for real-time in vivo bioimaging of cancer cell metastasis. An experimental nanobiotechnology approach was employed, involving the synthesis of near-infrared quantum dots, surface functionalization to enhance biocompatibility, physicochemical and optical characterization, and biological evaluation using metastatic cancer cell lines and small animal models. Optical analysis demonstrated high quantum yield, narrow emission bandwidth, and excellent photostability within the near-infrared window. In vitro assays confirmed high cell-labeling efficiency with minimal cytotoxicity, while in vivo imaging revealed sustained and high-contrast fluorescence signals that enabled continuous tracking of cancer cell migration and organ colonization. Ex vivo validation corroborated in vivo imaging findings. These results indicate that near-infrared quantum dots provide superior performance compared to conventional fluorescent probes for dynamic metastasis imaging. In conclusion, quantum dot–based near-infrared probes represent a powerful and versatile platform for real-time in vivo visualization of cancer metastasis, offering significant potential for advancing cancer research and diagnostic imaging.
