Cornea-SELEX for aptamers targeting the surface of eyes and liposomal drug delivery.

Cornea is the major barrier to drug delivery to the eye, which results in low bioavailability and poor efficacy of topical eye treatment. In this work, we first select cornea-binding aptamers using tissue-SELEX on pig cornea. The top two abundant aptamers, Cornea-S1 and Cornea-S2, could bind to pig cornea, and their values to human corneal epithelial cells (HCECs) were 361 and 174 nм, respectively.

Catalytic and biocatalytic degradation of microplastics.

In recent years, there has been a surge in annual plastic production, which has contributed to growing environmental challenges, particularly in the form of microplastics. Effective management of plastic and microplastic waste has become a critical concern, necessitating innovative strategies to address its impact on ecosystems and human health. In this context, catalytic degradation of microplastics emerges as a pivotal approach that holds significant promise for mitigating the persistent effects of plastic pollution.

Composite materials based on covalent organic frameworks for multiple advanced applications.

Covalent organic frameworks (COFs) stand for a class of emerging crystalline porous organic materials, which are ingeniously constructed with organic units through strong covalent bonds. Their excellent design capabilities, and uniform and tunable pore structure make them potential materials for various applications. With the continuous development of synthesis technique and nanoscience, COFs have been successfully combined with a variety of functional materials to form COFs-based composites with superior performance than individual components.
