PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

open access: yesAdvanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

A Simulated Microgravity Environment Causes a Sustained Defect in Epithelial Barrier Function. [PDF]

open access: yes, 2019
Intestinal epithelial cell (IEC) junctions constitute a robust barrier to invasion by viruses, bacteria and exposure to ingested agents. Previous studies showed that microgravity compromises the human immune system and increases enteropathogen virulence.

The Space Within: How Architected Voids Promote Tissue Formation

open access: yesAdvanced Materials, EarlyView.
This review explores the role of void spaces in tissue engineering scaffolds and examines four key methods for introducing porosity into hydrogels at different scales. It discusses sacrificial templating, microgels, phase separation, and 3D printing, highlighting principles, advantages, and limitations. It also addresses emerging strategies integrating

Comparative Characteristics of Corneal Confocal Microscopy after UV-A Cross-linking with Different Riboflavin Solutions in Experiment

open access: yesOftalʹmologiâ
Corneal cross-linking (CXL) has become the most common way of managing keratectasia. To date, the Dresden protocol (G. Wollensak et al., 2003) has acquired many modifications, in which the composition of the applied agents or modes of CXL procedure have ...

Arresting Microphase Separation Encodes Material Mechanics by Sculpting Microarchitectures and Local Polymer Enrichment

open access: yesAdvanced Materials, EarlyView.
Microarchitecture sculpting via phase separation programs hydrogel mechanics by creating globular, inverse globular, and spinodal structures. Spinodal architectures deliver superior toughness and energy dissipation, while ionic modulation through single polymer phase separation offers a simple, scalable route to tune mechanical properties ...

Structural Characterization of Insoluble Dextran Produced by Leuconostoc mesenteroides NRRL B-1149 in the Presence of Maltose

open access: yesFood Technology and Biotechnology, 2011
Leuconostoc mesenteroides NRRL B-1149 is known to produce dextran with 52 % α-(1→6) and 40 % α-(1→3) linkages. Low solubility of dextran in water is associated with the presence of high percentage of α-(1→3) linkages.

Characteristics of Zein-Dextran Conjugates Prepared by Ultrasound-assisted Maillard Reaction

open access: yesShipin gongye ke-ji
Zein, the main storage protein of corn, exhibits limited applications in the food industry due to its poor solubility. To enhance the solubility of zein and improve its functional properties, ultrasound-assisted Maillard reaction was performed to prepare

Tailored Xenogeneic‐Free Polymer Surface Promotes Dynamic Migration of Intestinal Stem Cells

open access: yesAdvanced Materials, EarlyView.
This study introduces a PoLymer‐coated Ultra‐stable Surface (PLUS), a nitrogen plasma‐treated poly(ethyleneglycoldimethacrylate), as a stable xenogeneic‐free platform for intestinal stem cell culture. PLUS enhances cell attachment, supports actin‐driven migration, and retains functionality after 3 years of storage. Promoting cytoskeletal reorganization,
