Merging data curation and machine learning to improve nanomedicines
Graphical abstract
Introduction
The medical use of nanomaterials has shown promising advancement in the field of drug delivery. From the first FDA-approved nanodrug Doxil to the clinical use of lipid nanoparticles for mRNA vaccines, numerous nanoparticles can efficiently and safely deliver small molecules, proteins, nucleic acids, or other active pharmaceutical ingredients (APIs) [1], [2], [3]. Encapsulation in nanoparticles improves drug solubility, stability, and potentially facilitates the crossing of biological barriers and the selective targeting to disease sites, when these pharmacologic advantages have not or cannot be engineered into APIs [4]. However, designing nanocarriers and optimizing the delivery strategy can be time-intensive, and typically involves a substantial amount of trial and error. Clinical translation of nanomedicines often does not follow pre-clinical development, often due to the complexity and heterogeneity of nanoparticles[5] To address these issues, advanced data analytics methods promise to accelerate and improve the nanomedicine development processes.
While the prediction of nanomaterial behavior in vivo is challenging due to a lack of systematic studies across material types, artificial intelligence (AI) platforms promise to improve and streamline nanomedicine development. Since 2007, when the term ‘nanoinformatics’ was coined [6], [7], there has been an explosion of nanomaterial-related data science efforts, which has generated large datasets with nanomaterial characterizations [7]. However, there is a disconnect between the scientists curating the databases and those utilizing AI. As a result, some AI platforms are developed using small-scale, project-specific datasets that lack translational values. In addition, non-standardized reporting metrics make it difficult to compare different material entities, and non-centralized databases are inaccessible to research groups who are not equipped with data mining skills. Herein, the aims of this review are to (1) review the most recent AI studies that capture the epitome of nanomedicine platform development, (2) introduce public databases focused on nanomaterial characterizations, and, most importantly, (3) advocate for a collaboration between the research groups developing AI platforms and nano-informaticians in order to increase the clinical utility of nanomedicine.

Introduction to ‘Nanoinformatics’ and Machine learning
Many science and engineering fields today are becoming more data-driven (ie. data analysis is increasingly powering experimental decision-making). Data science is a multidisciplinary field that combines mathematics and statistics to extrapolate meaningful insights from data [8], [9]. As a result of the increasing interest in medical applications of nanotechnology, a new field of data science has emerged. ‘Nanoinformatics’ bridges computer science, information technology, nanotechnology, and
Recent advances in nanomedicine using machine learning
Over the past decade, machine learning applications in biomedical science and engineering has gained popularity and changed the landscape of nanomedicine research. According to Web of Science, the number of publications with the keywords “nanomedicine” and “machine learning” or “AI” has increased 10 times within the past 10 years. Nanomedicine research has benefited from various machine learning studies, as many traditional methodologies are unable to delineate the complexity and heterogeneity of
Data curation for nanomedicine
Recognizing the need for a centralized nanomedicine database to strengthen analyses, nano-informaticians create platforms that accommodate the storage and sharing of heterogeneous nanomedicine data [6], [7], [10]. This process falls within a major area of data science - data curation. Historically originated in library science, data curation consolidates data from various sources into one database [96]. In addition to categorizing data into a useful presentation, data curation also involves
Conclusions and outlook
In the past decades, the field of nanomedicine has rapidly expanded preclinically and clinically. However, many practical obstacles have delayed the translation of most pre-clinical research into the clinic, including formulation difficulties/scale-up, unsatisfactory PK/PD, and costs [132]. We believe these issues can be ameliorated if the field can learn from the massive amounts of data already collected by the field. Recent advances in “big data” analytic approaches, including machine
