“…[19] Despite their interesting properties,methods to synthesize nanocups are only few including DNAo rigami, [20] block copolymer self-assembly, [21][22][23] polymerization-induced buckling, [12] chemical deformation, [24] and templating. [25][26][27][28] These methods have in common that the chemistry of the inside and outside of synthesized cups is typically identical. However,to enhance their selectivity towards interfaces or cargo,itwould be desirable to give cups aJ anus character,that is,adifferent chemistry on the inside and outside.F or the last two decades, Janus particles were synthesized from an umber of materials in various sizes.…”

We report on the formation of shape-and surfaceanisotropic Janus nanocups (JNCs) by evaporation-induced confinement assembly (EICA) of ABC triblock terpolymers. During microphase separation in spherical confinement, the triblockt erpolymer spontaneously adopted ah emispherical shape with an inner concentric lamella-lamella (ll) morphology.C ross-linking and disassembly of the microparticles resulted in well-defined JNCs with different chemistry on the inside and outside.B ys ynthesizing polymers with increasing length of the cross-linkable block, we tuned the mechanical stability of the nanocups,w hichi sr elevant to control opening and closing of the cup cavity.Weutilize the Janus properties for selective uptake of cargo exemplified by the filling of JNCs with polymer or gold nanoparticles.The directional properties of JNCs suggest applications in locomotion, oil-spill recovery, storage and release,t emplating,a nd as nanoreactors with attoliter volume.

“…iii) The flourishing development of GNPs with various morphologies provides many possibilities for the core selection of GVs. In addition to the GN, GN string, GNR, GNF, and Janus GN‐Fe 3 O 4 NPs that have successfully assumed the role of GV's cores, GNPs with other shapes could also be the promising cores of GVs . iv) The large cavity of GVs could be loaded with more functional substances.…”

Gold nanoparticles (GNPs), with tunable optical properties, bioinertness, and surface multivalent effect, have been widely explored for biomedical applications. As one classical type of GNPs‐based assemblies, plasmonic gold nanovesicles (GVs), with a hollow cavity, “solid skeleton” composed of GNPs cores and a “soft body” composed of functional polymers, have attracted considerable attention due to their tunable localized surface plasmon resonance, strong surface‐enhanced Raman scattering properties, and high photothermal conversion efficiency. This review summarizes recent advances in biomedical applications for plasmonic GVs. Firstly, the synthesis methods of GVs are mainly including self‐assembly and in situ gold growth methods. Secondly, the classification of GVs is described according to the morphology of GNPs cores. Thirdly, different biomedical applications of GVs are elaborated, including in vitro diagnosis, in vivo imaging, and in vivo therapy. Finally, the challenges and perspectives of GVs are discussed.

Since the extension of the Stöber method traditionally used in the synthesis of silica nanoparticles into the fabrication of resorcinol-formaldehyde nanospheres in 2011, significant progresses have been achieved in this exiting area of nano-resole-enabled synthesis of elegant nanostructures with versatile compositions and promising applications in various fields. To date, there are few reviews focused on this topic. In this minireview, we aim to provide an overview on recent developments, with the emphasis on nano-resoles as an enabling strategy in the synthesis of innovative materials. The history of nano-resoles and their distinct roles classified into four functions will be introduced. Clear understanding into this research field is vital for achieving rational design and controllable synthesis of a new generation of nano-resoles and their derived nanostructures.
