Highly Tunable and Cell‐Remodelable Thiol‐ene Alginate‐Peptide Crosslinked Hydrogels to Recreate Cellular and Organoid Microenvironments for Biofabrication

open access: yesAdvanced Healthcare Materials, EarlyView.
Norbornene‐functionalized alginate is crosslinked with a di‐thiolated peptide sequence cleavable by cell‐secreted matrix metalloproteinases and decorated with cell‐adhesion peptides upon exposure to UV. Thyroid follicles, endometrial and intestinal organoids are encapsulated in a gentle manner with high cell viability and correct phenotype ...

Skin‐Interfaced Therapeutic Patches for Wound Fluid Management and Transdermal Drug Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an integrated skin‐interfaced device combining microfluidics, hydrogel film technology, flexible electronics, and iontophoresis‐based transdermal delivery of PDRN to enhance wound healing. The device effectively manages wound fluid, maintains optimal moisture, and non‐invasively delivers therapeutic drugs.

Natural convection to air from an array of vertical parallel plates with discrete and protruding heat sources

open access: yesInternational Journal of Heat and Fluid Flow, 1995
Abstract Numerical and experimental studies are carried out on natural convection heat transfer to air from an array of vertical parallel plates with protruding and discrete heat sources, such as IC packages. Two-dimensional (2-D) Navier-Stokes and energy equations including heat conduction through the plates and heat sources are numerically solved ...

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia

open access: yesAdvanced Healthcare Materials, EarlyView.
This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can
