Recent Progress on Preparation of Anisotropic Block Copolymer Particles Self-Assembled in 3D Emulsion Droplets.

Self-assembly of block copolymers (BCPs) into anisotropic colloidal particles within 3D emulsion droplets has attracted considerable interest since the confined assembly in deformable geometries offers significant potential for designing and constructing specific anisotropic polymer materials for various applications. By precisely controlling the deformation of emulsion droplets, nucleation, and deposition sequence of BCP segments at the oil/water interface, various anisotropic polymer assembly particles with tunable shapes and internal structures can be generated. This review summarizes the recent advancements in the design and formation of anisotropic polymer assembly particles via confined assembly of BCPs, including an overview of emulsification techniques and methods, the regulation of particle shapes and internal structures, as well as the diverse applications of resulting anisotropic particles.

However, the controllable assembly and oriented growth of nanorods in solution without external template assistance remains a great challenge. Here, we report a facile Hofmeister-effect-based assembly strategy for fabricating ordered arrangements of polyethylene glycol-tethered gold nanorods (AuNRs@PEG) with controlled orientation and dimension.

Bupivacaine multivesicular liposomes/meloxicam nanocrystals in a thermosensitive gel adapted to the "microenvironment" for long-term analgesia.

Association of urinary heavy metal combined exposure with periodontitis among US adults from NHANES 2011-2014.

Some heavy metals are associated with periodontitis; whereas most of these associations have focused on individual metal, there are no specific studies on the effects of combined heavy metal exposure on periodontitis. We conducted an analysis on the association between urinary heavy metal exposure and periodontitis in participants aged 30 years and older using multiple logistic regression and Bayesian kernel machine regression (BKMR). This analysis was performed on data from the National Health and Nutrition Examination Survey from 2011 to 2014.
