It's primitive... but it works... mostly...

I am pleased to share that I successfully coupled the laser radiation into the chip.

After two weeks of learning about the concepts of the micro-ring resonators (#MRR) and attempting to capture the resonances, I finally achieved my goal.

The main challenge I faced was accurately cutting the optical fiber and determining the optimal distance and angle between the fiber and the #waveguide for effective coupling. This process required a significant amount of trial and error. Additionally, for an entire week, I unknowingly worked with a chip that had broken couplers. When I adjusted the z-axis, I accidentally damaged the couplers with the fiber. Fortunately, I have a sufficient number of chips available for multiple trials.

How are the #microelectronic #bioelectronic chips produced?

The production starts from the blank wafers. Layering follows, where insulating and conductive materials are deposited onto the wafer. The #wafer is then covered with photoresist, and UV light is shone through a photomask to pattern the circuit of the sensor. Next comes the etching process, using chemicals or plasma to remove areas without photoresist. Doping is applied afterwards to alter the electrical properties of the silicon.
These steps are repeated in cycles to build the complex interconnected structure of the chip. Subsequently, layers of metal are deposited to establish connections between the circuit elements. Once completed, the wafers are tested for defects and then packaged .

For a demonstration of this process, check out the video from #ihpmicroelectronics (https://www.ihp-microelectronics.com/news-2/mediathek/videos). In the previous post, we showed how the #silicon chip originated from this wafer.

The picture shows a full wafer glued to blue tape for chip separation by sawing, from which some #biosensor chips have already been taken.

"Here we report on voltage-gated solid-state nanopores by electrically tunable chemical reactions. We demonstrate repetitive precipitation and dissolution of metal phosphates in a pore through manipulations of cation flow by transmembrane voltage. Under negative voltages, precipitates grow to reduce ionic current by occluding the nanopore, while inverting the voltage polarity dissolves the phosphate compounds reopening the pore to ionic flux."

A change of scenery now and then leads to new synaptic connections and changes in the #brain - even in mice. A group of researchers implanted #biosensor arrays with 4096 electrodes into the brains of #mice and kept one of two groups in a well-appointed dwelling. Certain behaviors, such as changing rooms, were rewarded. Subsequent brain analyses showed the positive effects of changing environments, e.g., on #neuronal dynamics.

O sweet biosensor of the future
So close, yet so far from us yet
A haven of hope in the darkness
A light to dispel our worry and fret
Your promise carries us forward
To a time filled with hope and cheer
A brighter future we can look to
Where our loved ones will no longer fear
