Wavelength‐Selective Light‐Controlled Stepwise Photolysis from Single Gold Nanoparticles

A light‐controlled sequential photolysis system is developed based on gold nanoparticles to release payloads in a wavelength‐dependent manner. With this system, stepwise, wavelength‐selective payload release is realized from single nanoparticle in live cells. The ability of light‐induced sequential release is ultimately useful to provide approaches...

Human Oral Motion‐Powered Smart Dental Implant (SDI) for In Situ Ambulatory Photo‐biomodulation Therapy

An ambulatory photo‐biomodulation therapy using a seamless, human oral motion‐powered Smart Dental Implant (SDI) is presented. Under chewing and brushing motions, the piezoelectric dental crown activates a micro‐light emitting diodes (LED) via an associate circuitry. Using primary human gingival keratinocytes as a model host and P. aeruginosa LPS as...

Engineered Perineural Vascular Plexus for Modeling Developmental Toxicity

Current models of in vitro brain development fail to mimic mechanisms in vivo, partly as they use animal‐derived matrices. The current study incorporates differentiated cell lines in a fabricated synthetic hydrogel in a microfluidics plate to recapitulate perineural vascular plexus in vivo. By analyzing endpoints such as growth factors, metabolites...

Designer Descemet Membranes Containing PDLLA and Functionalized Gelatins as Corneal Endothelial Scaffold

Innovative ultrathin carriers for corneal endothelial cells are developed that consisted of a polyester base and a top layer of gelatin. The membranes supported the characteristic hexagonal morphology and correct phenotype of corneal endothelial cells while exhibiting similar growth rates as the positive control. As a consequence, the proposed membranes...

Bioresorbable, Wireless, Passive Sensors as Temporary Implants for Monitoring Regional Body Temperature

Fully bioresorbable, wireless, battery‐free temperature sensors enable measurements of local internal body temperatures over clinically relevant timeframes and then ultimately disappear completely in the body, thereby eliminating the need for extraction surgeries. Potential applications include monitoring of processes associated with wound healing and...
