Unlock the Walnut: How a Pectin‐Rich Suture Tissue and Moisture‐Driven Crack Formation Induce Shell Splitting and Facilitate Seed Germination

open access: yesAdvanced Functional Materials, EarlyView.
Walnut seeds are enclosed in a remarkably strong shell made of sclerenchyma, separated by a pectin‐rich suture tissue. Different cell shapes and chemical composition of this tissue point to an opening mechanism, which is triggered by cyclic humidity changes.

A Peptide Nucleic Acid‐Functionalized Heterojunction Thin Film Transistor as a Scalable and Reusable Platform for Label‐Free Detection of MicroRNA

open access: yesAdvanced Functional Materials, EarlyView.
A miniaturized, label‐free, and enzyme‐free biosensor (miR‐TFT) enables direct electrical detection of microRNA (miRNA) with single‐nucleotide specificity and a detection limit of 0.6 fM. Built on a tri‐channel In2O3/ZnO heterojunction and functionalized with bespoke peptide nucleic acid (PNA) probes, the device is robust, reusable, and compatible with

The Effect of Strontium on Growth and Development of Arrested Two-Cell NMRI Mouse Embryos

open access: yesMajallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2011
Introduction: Decrease in the rate of the growth and development embryos and their arrest in a certain developmental step e.g. two- Celll block, could be the reason of infertility in some couples reffering to fertility and infertility center.

Towards High‐Acuity Vision Restoration: Hybrid Retinal Prosthesis Composed of a High‐Density Multielectrode Array Integrated With Glutamatergic Cells

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a novel Hybrid Retinal Implant (HRI), composed of a high‐density electrode array integrated with glutamatergic neurons to overcome key limitations of current retinal prostheses. The significant reduction of activation threshold and of electrode cross‐talk yields in an improved spatial resolution.
