Organic framework polymers have attracted much interest due to the enormous potential design space offered by the atomically precise spatial assembly of organic molecular building blocks. The morphology control of organic frameworks is a complex issue that hinders the development of organic frameworks for practical applications. Biomimetic self‐assembly is a promising approach for designing and fabricating multiple‐functional nanoarchitectures. A bioinspired hollow flower‐like organic framework nanosphere heterostructure comprised of carbon nitride and polydopamine (g‐C3N4@PDA) is successfully synthesized via a mild and green method. This heterostructure can effectively avoid the agglomeration of nanosheets to better access the hollow nanospheres with high open‐up specific surface area. The electron delocalization of g‐C3N4 and PDA under visible light can largely promote photoelectron transfer and enhance the photocatalytic activity of the g‐C3N4@PDA. Furthermore, the g‐C3N4@PDA can effectively enhance the generation of reactive oxygen species under irradiation, which can lead to cell apoptosis and enhance the performance for cancer therapy. Therefore, the as‐prepared g‐C3N4@PDA provides a paradigm of highly efficient photocatalyst that can be used as nanomedicine toward cancer therapy. This study could open up a new avenue for exploiting more other potential hollow nanosphere organic frameworks.

The prime-mover for the arrival of the Neolithic in Island Southeast Asia is thought to be the expansion of rice farmers speaking an Austronesian language and coming from the north (see Spriggs, above). Much less is known of the indigenous hunter-gatherers and their interaction with the new farming communities. The mutually occupied area, in the definition of Peter Bellwood, was a ‘Friction Zone’, where two radically different cultures met. This paper emphasises how much land, and information, was lost when the rising sea drowned Sundaland, an area the size of India, and brings to bear archaeological and DNA evidence to emphasise the continuing role of hunter-gatherers in the later prehistory of Southeast Asia.
