The integration of light sources on a photonic platform is a key aspect of the fabrication of self-contained photonic circuits with a small footprint that does not have a definitive solution yet. Several approaches are being actively researched for this purpose. In this work we propose optoelectronic tweezers for the manipulation and integration of light sources on a photonic platform and report the positional and angular accuracy of the micromanipulation of standard Fabry-Pérot InP semiconductor laser die. These lasers are over three orders of magnitude bigger in volume than any previously assembled with optofluidic techniques and the fact that they are industry standard lasers makes them significantly more useful than previously assembled microdisk lasers. We measure the accuracy to be 2.5 ± 1.4 µm and 1.4 ± 0.4° and conclude that optoelectronic tweezers are a promising technique for the micromanipulation and integration of optoelectronic components in general and semiconductor lasers in particular.

The construction of a nanozyme-enzyme hybrid cascade system is an effective protocol to optimize the performance of biosensors. Yet, the integration has limitations due to the lack of harmonious collaboration between nanozyme and enzyme. Herein, we have constructed an efficient enzymatic cascade system by utilizing the base complementary pairing and the targeting capability of DNA tweezers to combine DNA-regulated copper nanoflowers (CuNFs) with acetylcholinesterase (AChE).

Optoelectronic tweezers (OETs) represent a flexible, high-throughput method for manipulating micro/nano particles or cells. This technique involves not only light-actuated dielectrophoresis (LDEP) but also light-actuated AC electroosmosis (LACE), which occurs concurrently in OETs devices. Despite this, the combination of negative LDEP and LACE has been relatively unexplored in previous research.

Field-controlled micromanipulation represents a pivotal technique for handling microparticles, yet conventional methods often risk physical damage to targets. Here, we discovered a completely new mechanism for true noncontact manipulation through photothermal effects, called thermal-optical tweezers. We employ a laser self-assembly photothermal waveguide (PTW) for dynamic microparticle manipulation.
