Perylenediimide-cored dendrimers and their bioimaging and gene delivery applications

In the past few years, perylenediimide-cored (PDI-cored) dendrimers have been successfully prepared and applied in various fields. In this review, we focus on the structural design and synthesis strategies of PDI-cored dendrimers that involve convergent and divergent synthesis approaches. When building the outer shell of PDI-cored dendrimers, first hydrophobic and then hydrophilic macromolecules are introduced. The advantages of water-soluble PDI-cored dendrimers include strong red fluorescence, excellent photostability, low cytotoxicity, high quantum yield, and versatile surface modification. The biological application of water-soluble PDI-cored dendrimers is broad, including fluorescence live-cell imaging, fluorescent labeling, and gene delivery, owing to the rapid development of these materials in the past decade. The challenges and outlooks in this field will also be discussed.     

Short review on liquid membrane technology and their applications in biochemical engineering

As a branch of membrane separation technology, liquid membrane has attracted great attention and expanded investigations in biological chemical engineering, with life and health concern in ecosystems.Composed of membrane solvent and mobile carrier, liquid membrane was acquired of function, performing the facilitated mass transfer across the diffusive solvent, so as for the separation and delivery achievement with efficacy. In this review, two types of liquid membrane are mainly focused, respecti...
