Molecular self-assembly has received considerable attention in biomedical fields as a simple and effective method for developing biomolecular nanostructures. Self-assembled nanostructures can exhibit high binding affinity and selectivity by displaying multiple ligands/receptors on their surface. In addition, the use of supramolecular structure change upon binding is an intriguing approach to generate binding signal. Therefore, many self-assembled nanostructure-based biosensors have been developed over the past decades, using various biomolecules (e.g., peptides, DNA, RNA, lipids) and their combinations with non-biological substances. In this review, we provide an overview of recent developments in the design and fabrication of self-assembling biomolecules for biosensing. Furthermore, we discuss representative electrochemical biosensing platforms which convert the biochemical reactions of those biomolecules into electrical signals (e.g., voltage, ampere, potential difference, impedance) to contribute to detect targets. This paper also highlights the successful outcomes of self-assembling biomolecules in biosensor applications and discusses the challenges that this promising technology needs to overcome for more widespread use.

The worldwide population of the elderly is steadily increasing, and even more so in Korea, thus causing an increase in the osteoporotic fracture prevalence. Osteoporotic fracture is a serious injury that can decrease quality of life, and can also produce major social problems when it causes mortality. Preventing such fractures from happening in the first place is of utmost importance but once a fracture does occur, it is important to select appropriate treatment modalities to prevent secondary fractures. Recently, with the increase of life expectancy, it has become favorable to perform surgical fixation for significantly displaced osteoporotic fractures and use early rehabilitation programs to return the patient to normal body performance as soon as possible. To do so, it is important to accurately assess the location and the degree of the fractures in order to select appropriate treatment modalities. Furthermore, it is important to prevent secondary fractures from happening once the previous fractures heal.
