Specular microscopic and histopathologic findings in the corneal endothelium were compared after the injection of liquid silicone into the anterior chamber of both eyes in 15 rabbits. The findings demonstrated serious damage to the endothelium in the area of contact of liquid silicone with the posterior surface of the cornea and disclosed some problems in the interpretation of specular microscopic findings. An abnormal endothelial mosaic can be probably found even in a zone of preserved intercellular borders or in a zone with a relief of the bases of extinct endothelial cells.

Introduction: In facial cosmetic surgery, injectable liquid silicone has been used to augment the cheek and the lips and to camouflage facial wrinkles. However, complications started to arise in 1964 as postoperative silicone granuloma formation. The purpose of this study is to introduce our experience in facial reconstruction after injectable silicon oil with a sequential 3-step approach: transoral surgical excision, full-face fat grafting, and hyaluronic acid filler.

Plasmonic Slippery Surface for Surface-Enhanced Raman Spectroscopy and Protein Adsorption Inhibition.

Anal Chem

January 2025

Department of Atomic and Molecular Physics, Manipal Academy of Higher Education, Manipal 576104, India.

Slippery liquid-infused porous surfaces (SLIPSs) are a class of surface that offers low contact angle hysteresis and low tilt angle for water droplet shedding. This property also endows the surface with pinning-free evaporation, which in turn has been exploited for analyte concentration enrichment for Surface Enhanced Raman Spectroscopic applications and antibiofouling. Herein, we demonstrate a facile approach for creating SLIPS with low contact angle hysteresis and low tilt angle for water shedding by coating the equal-volume mixture of polydimethylsiloxane (PDMS) and silicone oil.

Coaxial Direct Ink Writing of Cholesteric Liquid Crystal Elastomers in 3D Architectures.

Adv Mater

January 2025

Department of Materials Science and Engineering, University of Pennsylvania, 3231 Walnut Street, Philadelphia, PA, 19104, USA.

Cholesteric liquid crystal elastomers (CLCEs) hold great promise for mechanochromic applications in anti-counterfeiting, smart textiles, and soft robotics, thanks to the structural color and elasticity. While CLCEs are printed via direct ink writing (DIW) to fabricate free-standing films, complex 3D structures are not fabricated due to the opposing rheological properties necessary for cholesteric alignment and multilayer stacking. Here, 3D CLCE structures are realized by utilizing coaxial DIW to print a CLC ink within a silicone ink.

Chemo-Mechanical Due-Biomimetic Approach for Ultra-Stable Adsorption Across Multiple Scenarios.

Small Methods

January 2025

The unique adhesion capabilities of soft-bodied creatures such as leeches and octopuses have provided considerable inspiration for the development of artificial adhesive materials. However, previous studies have either focused on the design of sucker structures or concentrated on the synthesis of adhesive materials, with the combination of these two aspects not yet having been deeply investigated. In this study, inspired from leech's unique adsorption ability, a biomimetic approach is proposed that combined artificial sucker and mucus, to achieve remarkable adhesion stability on rough surfaces using 5 cm diameter silicone suction cups.

This study investigated silicone composites with distributed boron nitride platelets and carbon microfibers that are oriented electrically. The process involved homogenizing and dispersing nano/microparticles in the liquid polymer, aligning the particles with DC and AC electric fields, and curing the composite with IR radiation to trap particles within chains. This innovative concept utilized two fields to align particles, improving the even distribution of carbon microfibers among BN in the chains.
