A model that closely resembles human excessive myopia can be prepared by mounting a minus lens (2) and a protector (4) to a juvenile mouse, the minus lens having an angle and a width adjustable in response to growth of the mouse. Further, this model analysis shows that myopia induction causes endoplasmic reticulum stress in a sclera and the endoplasmic reticulum stress induces myopia. Furthermore, it is revealed that an endoplasmic reticulum stress suppressant, particularly, phenylbutyrate and tauroursodeoxycholic acid act as a myopia prevention / suppression agent.

The large-scale artificial synaptic device arrays based on the organic molecule-nanowire heterojunctions with tunable photoconductivity are proposed and demonstrated. The organic thin films of p-type 2,7-dioctyl[1]benzothieno[3,2-b][1] benzothiophene (C8-BTBT) or n-type phenyl-C61-butyric acid methyl ester (PC61BM) are used to wrap the InGaAs nanowire parallel arrays to configure two different type-I heterojunctions, respectively. Due to the difference in carrier injection, persistent negative photoconductivity (NPC) or positive photoconductivity (PPC) are achieved in these heterojunctions. The irradiation with different wavelengths (solar-blind to visible ranges) can stimulate the heterojunction devices, effectively mimicking the synaptic behaviors with two different photoconductivities. Evidently, these photosynaptic devices are illustrated with retina-like behaviors and capabilities for large-area integration, which reveals their promising potential for artificial visual systems.
