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.

Magnetic medical microrobots with memory-capable genetic circuits
Autonomous microrobots can reach hard-to-access regions in the human body for minimally invasive therapy. However, their microscale size limits the integration of on-board memory, making their operation dependent on external controls. Here, we develop a magnetic probiotic microrobot integrated with memory-capable genetic circuit to execute autonomous antitumor treatment. Through a one-time magnetic hyperthermia trigger, the biological thermal sensor in the microrobot perceives temperature change and activates the memory module Bxb1-ssrA-attB-P7-attP, transferring the microrobots into a therapeutic state to continuously degrade fibrin and soften the tumor microenvironment. The genetic memory remains active for at least 12 days. A synergy toward deep tumor penetration is subsequently established between the memory-encoded softening and the physical penetration through magnetically controlled wave-like locomotion of microrobots. Compared with memory-absent microrobots, the proposed microrobots achieve a 6.70-fold tumor matrix stiffness reduction and boost in vivo anticancer efficacy from 21.86 to 87.52%. Beyond oncology, the proposed system establishes a generalizable framework of memory-encoded medical microrobots.

Prompt-Only Gene-Circuit Modeling with a Large Language Model Simulates the synNotch Spheroids
Morphogenesis emerges from gene regulatory circuits that translate biochemical cues into spatially organized cell fates; yet, constructing quantitative simulations of these processes remains technically demanding. Here, we present a prompt-only pipeline in which a large language model (LLM) automatically generates CompuCell3D (CC3D) simulations directly from natural-language biological specifications. Using the canonical synNotch spheroid assay as a benchmark, we show that the LLM-generated code captures key features of contact-dependent signaling, cadherin-mediated adhesion, and multicellular sorting dynamics without manual programming. Baseline simulations exhibited the expected qualitative ordering of inducer-responder activation but revealed fragmentation into multiple spheroids, implicating premature reciprocal signaling as a kinetic failure mode. Incorporating a cumulative contact-duration threshold for synNotch activation rescued robust single-spheroid formation, suggesting that sustained cell-cell interactions are a critical design principle for this pattern. Our results establish conversational LLM guidance as a powerful accelerator for multiscale modeling, collapsing the steep learning curve of CC3D into a dialog-driven workflow. This framework enables nonspecialists to test gene-circuit hypotheses in silico and provides a generalizable route toward rapid, mechanism-level exploration of developmental design principles.
