Design of a broadband SiN waveguide amplifier based on a gain medium of ion-sliced titanium-doped sapphire.

In recent years, significant progress has been made in the on-chip integration of Ti:sapphire amplifiers and lasers, showing great potential in device miniaturization, cost reduction, and mass production. However, the further integration of such devices on standard CMOS platforms has been challenging due to its limits on the wafer bonding method between gain materials and substrates. Here, we present a novel, to the best of our knowledge, SiN on-chip broadband optical waveguide amplifier scheme with an ultra-wide bandwidth of 650-900 nm and a peak gain of 28 dB based on an ion-sliced Ti:sapphire platform.

A Label-Free Electrochemical Aptamer Sensor for Sensitive Detection of Cardiac Troponin I Based on AuNPs/PB/PS/GCE.

Cardiac troponin I (cTnI) monitoring is of great value in the clinical diagnosis of acute myocardial infarction (AMI).

PS microspheres were synthesized by emulsion polymerization and then dropped onto the glassy carbon electrode (GCE); PB and AuNPs were electrodeposited on the electrode in corresponding electrolyte solutions step by step.

The Enhanced Photoluminescence Properties of Carbon Dots Derived from Glucose: The Effect of Natural Oxidation.

The investigation of the fluorescence mechanism of carbon dots (CDs) has attracted significant attention, particularly the role of the oxygen-containing groups. Dual-CDs exhibiting blue and green emissions are synthesized from glucose via a simple ultrasonic treatment, and the oxidation degree of the CDs is softly modified through a slow natural oxidation approach, which is in stark contrast to that aggressively altering CDs' surface configurations through chemical oxidation methods. It is interesting to find that the intensity of the blue fluorescence gradually increases, eventually becoming the dominant emission after prolonging the oxidation periods, with the quantum yield (QY) of the CDs being enhanced from ~0.
