The flexible and precise manipulation of droplets on an air-liquid interface with complex functions remains challenging. Herein, we propose a smart strategy for excellently manipulating target droplets by decanol liquid lenses. A moveable surface tension gradient field generated by decanol liquid lenses is responsible for realizing various functions of transportation, launching and splitting of target droplets. With such fascinating features, directional long-distance transportation and on-demand droplet coalescence are enabled. Moreover, paw-like liquid lenses are constructed, which realizes a complex process, including collection, capture, transportation and release of target droplets. Remarkably, this strategy can also be applied to manipulate particles and liquid marbles other than droplets, eliminating the limitation of object properties. This work offers a smart strategy for manipulating micro-objects, which shows great potential in applications such as lab-on-a-chip, diagnostics, analytical chemistry and bioengineering,

Polymer-dispersed liquid crystals (PDLCs) stand at the intersection of polymer science and liquid crystal technology, offering a unique blend of optical versatility and mechanical durability. These composite materials are composed of droplets of liquid crystals interspersed in a matrix of polymeric materials, harnessing the optical properties of liquid crystals while benefiting from the structural integrity of polymers. The responsiveness of LCs combined with the mechanical rigidity of polymers make polymer/LC composites-where the polymer network or matrix is used to stabilize and modify the LC phase-extremely important for scientists developing novel adaptive optical devices.

Lubrication surfaces reduce the risk of cross-contamination and enhance the long-term stability of medical devices, which holds significance in the realm of antifouling medical materials. However, the complexity of constructing micronano structures to immobilize lubricating fluids and the fluorine content typically found in silane coupling agents restrict their widespread adoption. In this study, we prepared a biomimetic lubricating coating (BLC) through the one-step self-assembly of octadecyltrichlorosilane and oil infusion.

This review examines the history of contact lens (CL) care products, particularly focusing on hard contact lenses (HCLs) like those made from polymethyl methacrylate and rigid gas permeable (RGP) materials. Although literature on CL history is extensive, there is limited information on the history of CL care products, especially in Japan. This review uses advertisements from the Journal of the Japan Contact Lens Society from 1959 to 2023 to trace the evolution of these products.

Article Synopsis
- Lubricant-mediated surfaces face challenges like lubricant loss and poor clarity for antifouling purposes.
- Inspired by globefish skin, slippery Liquid-Like Surfaces (LLSs) use cyclodextrin-eugenol complexes and flexible silicone chains to effectively kill attached organisms and prevent fouling.
- LLSs show excellent antifouling and mechanical properties while maintaining transparency in various water environments, lasting up to 90 days on coated lenses in seawater.
Interfacial Dripping Faucet: Generating Monodisperse Liquid Lenses.

We present a surface analog to a dripping faucet, where a viscous liquid slides down an immiscible meniscus. Periodic pinch-off of the dripping filament is observed, generating a succession of monodisperse floating lenses. We show that this interfacial dripping faucet can be described analogously to its single-phase counterpart, replacing surface tension by the spreading coefficient, and even undergoes a transition to a jetting regime.
