Chitosan (CS) has physicochemical properties including solubility, crystallinity, swellability, viscosity, and cohesion, along with biological properties like biocompatibility, biodegradation, antioxidant, antibacterial, and antitumor effects. However, these characteristics of CS are greatly affected by its degree of deacetylation, molecular weight, pH and other factors, which limits the application of CS in biomedicine. The modification of CS with catechol-containing substances inspired by mussels can not only improve these properties of CS, but also endow it with self-healing property, providing an environmentally friendly and sustainable way to promote the application of CS in biomedicine. In this paper, the properties of CS and its limitation in the biomedical filed are introduced in detail. Then, the modification methods and properties of substances with catechol groups inspired by mussels on CS are reviewed. Finally, the applications of modified CS in the biomedical field of wound healing, drug delivery, anticancer therapy, biosensor and 3D printing are further discussed. This review can provide valuable information for the design and exploitation of mussel-inspired CS in the biomedical field.

Preclinical stroke research faces a critical translational gap, with animal studies failing to reliably predict clinical efficacy. To address this, the field is moving toward rigorous, multicenter preclinical randomized controlled trials (mpRCTs) that mimic phase 3 clinical trials in several key components. This collective statement, derived from experts involved in mpRCTs, outlines considerations for designing and executing such trials.

Optical manipulation techniques have been widely applied in the biomedical field. However, the key issues limiting the efficiency of optical manipulation techniques are the weak driving force of optical scattering and the small working range of optical gradient forces. The optothermal Marangoni convection enables effective control of flow fields through optical means, and particle manipulation based on this mechanism offers advantages such as a wide working range, strong driving force, and high flexibility.

Mechanoglycobiology has emerged as a rapidly expanding interdisciplinary field that involves chemistry, biology, and engineering. Despite the great advancements in this field, in-depth investigation of mechanoglycobiology remains challenging due to the complex nature of glycans and cell glycocalyx, as well as the difficulty to mechanically target these biomolecules. To address the issues, novel methods and models have been established to facilitate the investigation of glycan-mediated mechanosensing and mechanotransduction.

Oral cancer is a major global health burden, ranking sixth in prevalence, with oral squamous cell carcinoma (OSCC) being the most common type. Importantly, OSCC is often diagnosed at late stages, underscoring the need for innovative methods for early detection. The oral microbiome, an active microbial community within the oral cavity, holds promise as a biomarker for the prediction and progression of cancer.

The physical environment exerts a profound influence on microbial life. The directional movement of cells in response to their physical environment is understood as taxis, which has been studied in biology as chemotaxis, phototaxis, gravitaxis and so forth. These taxis are induced by physiological, physical or both factors.
