Its strength lies in the ability to process and analyze complex, high-dimensional datasets, providing predictive capabilities and uncovering intricate patterns that would otherwise remain hidden through traditional analytical methods. One of the core applications of machine learning in biomedicine is predictive modeling using measurable patient or environmental data. For instance, in psychiatric medicine, ML algorithms have been leveraged to predict mood fluctuations based on passive data collected from smartphones, such as behavioral patterns and speech features. In neuroscience, machine learning has enabled the decoding of neural activity to infer cognitive states and motor intentions, which has significantly advanced brain-computer interfaces (BCIs) and neuroprosthetics. Moreover, machine learning functions as a benchmark against which humangenerated models can be evaluated. This not only helps identify gaps in existing theories but also fosters the discovery of novel biological mechanisms. ML excels in capturing nonlinear relationships and handling temporal dynamics, both of which are prominent in complex biological systems. As biomedical datasets continue to grow in volume, velocity, and variety, the limitations of human cognition in interpreting such data are increasingly mitigated by the scalability and adaptability of AI-driven approaches.

In the field of neural decoding, ML methods—especially deep neural networks and ensemble learning techniques—have consistently outperformed traditional linear models. These algorithms have proven effective in capturing the rich, nonlinear interactions between neural signals and behavioral outputs. Similarly, in neural encoding, ML provides a more sophisticated understanding of how external stimuli are represented within the brain, setting new standards for computational neuroscience. Importantly, the growing accessibility of AI tools—ranging from user-friendly software platforms to automated machine learning (AutoML) systems—has empowered biomedical researchers without extensive computational backgrounds. These tools allow scientists to focus on formulating hypotheses and interpreting outputs, rather than on the underlying algorithmic details.

Text mining, another powerful ML application, has streamlined the extraction of biological knowledge from vast scientific publications. Coupled with NLP, ML allows for automated annotation of gene functions, drug-target predictions, and the identification of molecular interactions. In systems biology, ML supports the development of computational models to simulate and predict biological network behaviors, including genetic, protein-protein, and metabolic networks. Algorithms such as Bayesian networks and genetic algorithms are commonly used to infer gene regulatory networks and explore phenotype-genotype relationships.

In parallel, the case study of drug delivery systems (DDS), particularly in the realm of immunotherapeutics, highlights the convergence of bioengineering, biomaterials, and computational approaches. Oral delivery of immunotherapies offers substantial advantages in terms of ease of administration and patient compliance, yet it presents formidable challenges such as enzymatic degradation, pH variability, and mucosal barriers in the gastrointestinal (GI) tract. The GI tract, rich in immune cells, provides a unique opportunity for site-specific immune modulation. Oral administration can induce systemic tolerance, potentially minimizing antidrug antibody responses and improving therapeutic efficacy. Immunotherapeutics including interleukins, monoclonal antibodies, nucleic acids (e.g., mRNA, DNA), and smallmolecule modulators benefit from biomaterial-based DDS that target specific intestinal regions.

Biomaterials with mucoadhesive properties, such as thiolated polymers, enhance the residence time of drugs by forming covalent bonds with mucosal surfaces, thereby improving local delivery for diseases like inflammatory bowel disease (IBD) and ulcerative colitis. Innovative DDSs like self-nanoemulsifying drug delivery systems (SNEDDS), in conjunction with mucolytic agents, enhance mucosal penetration and bioavailability. These systems allow precise delivery of anti-inflammatory agents, growth factors, and vaccines, thereby enabling targeted immune modulation. To traverse the epithelial barrier, advanced strategies utilize passive and active transport mechanisms including transcytosis, carriermediated diffusion, and the incorporation of cell-penetrating peptides (CPPs). Technologies such as molecular motors and transient permeabilizers facilitate systemic drug absorption, leading to more effective immune responses against mucosal infections. Emerging biomaterials—both natural (e.g., chitosanbased nanoparticles) and synthetic (e.g., PEGylated systems)— demonstrate promising capabilities for oral immunotherapeutic delivery. Devices like MucoJet, which injects immunotherapeutics through mucosal surfaces using pressurized microjets, exemplify innovation in this space. These technologies are instrumental in enhancing the pharmacokinetics and therapeutic index of orally administered biologics. Furthermore, next-generation systems are progressing towards 4D bioprinting—dynamic drug delivery platforms that respond to environmental stimuli (e.g., pH, temperature, enzymes). These adaptive materials offer enhanced spatiotemporal control of drug release, furthering the goals of personalized and precision medicine. Despite remarkable progress, challenges remain. Key obstacles include maintaining drug stability, ensuring reproducible targeting, controlling manufacturing costs, and navigating regulatory hurdles for clinical translation. Nevertheless, the integration of biomaterials, AI-driven modeling, and advanced DDS presents a transformative approach to immune engineering and therapeutic development.

Precision medicine is at the forefront of transformative healthcare, offering the promise of personalized treatments tailored to an individual’s unique genetic makeup, lifestyle, and environment. Despite its immense potential, several challenges must be overcome to ensure its widespread adoption and clinical success. This section explores the recent advancements in gene editing and precision medicine, while also addressing the hurdles and opportunities that lie ahead. One of the most revolutionary technologies driving this transformation is genome editing, particularly tools like CRISPR-Cas9. These techniques enable targeted modifications to the genome, allowing for the correction of disease-causing mutations and offering new avenues for the treatment of previously intractable genetic disorders. Gene editing not only improves therapeutic precision but also opens doors to curative treatments for rare and complex diseases. However, implementing gene editing in clinical settings presents challenges such as the assessment of benefit-risk ratios, especially in cases involving small patient populations and rare diseases. Traditional clinical trial methodologies often fall short in these scenarios. As a result, novel statistical frameworks, such as pairwise comparisons of patient outcomes, are emerging as essential tools for evaluating treatment efficacy and safety in precision medicine.

Another major driver of precision healthcare is populationscale genomics. Initiatives like Estonia’s 100,000 Genomes Project exemplify the growing trend of utilizing genomic data at a national level to identify disease susceptibilities and optimize therapeutic interventions well before disease onset. This proactive approach shifts the healthcare paradigm from reactive treatment to preventive and predictive care. While the advancements are substantial, numerous challenges persist.
