The intervention of AI and ML generated Xenobots in the perspective of future technology: a review.
The evolution of synthetic mini-robots has contributed much to the field of science and technology. Still, of now, computational technology has shifted to generate AI-based robots from the living matter of Amphibian cells by utilizing evolutionary algorithms. In this aspect, we have discussed the evolution, role, applications, and ethical considerations of the Xenobots (the world's first living, programmable organisms) in this challenging artificial intelligence age. The various techniques involved in programming the xenobots were discussed, such as cell harvesting and culturing, computational design and simulation, assembly and bio-printing, cell differentiation and integration, machine learning and AI integration, etc. Moreover, they find their applications and promise significance in various fields, including medicine and health care. Finally,ethical considerations were discussed to emphasize safety, ensuring responsible development and deployment in various fields.

Ethical Considerations in Personal Health Large Language Models
Personal health large language models (PH-LLMs) have rapidly evolved from research prototypes into consumer-facing, data-linked systems that support symptom triage, medication questions, mental health check-ins, and longitudinal self-management. Their direct-to-consumer use without clinical oversight creates a distinct ethical risk profile that general artificial intelligence governance frameworks do not fully address. This viewpoint focuses on text-based, platform-mediated PH-LLMs and synthesizes PH-LLM-specific challenges across 6 domains: privacy, accuracy, equity, transparency, human-artificial intelligence interaction, and regulatory governance. These risks may be amplified by health literacy gaps, longitudinal data aggregation, persuasive conversational design, and fragmented oversight across the consumer-clinical boundary. Grounded in the 4 principles of biomedical ethics, we propose a governance framework that operationalizes beneficence, nonmaleficence, autonomy, and justice through design and deployment controls, including health literacy-aligned communication, crisis and pharmacological safeguards, hallucination mitigation, role disclosure, granular consent, fairness auditing, and accessible design. We further outline implementation mechanisms, including risk-tiered certification, tiered accountability, and postdeployment oversight through adverse-event reporting, transparency reporting, and independent safety evaluation. This framework is intended as an evidence-informed but partly anticipatory approach to governing PH-LLMs in personal health management.
