around, if there that simple to make, everyone should have a USB microscope,
to connect to the computer, complete with a neural network program to detect

	<htmltext>Here are some more details from the abstract of a relevent paper:<p><div class="quote"><p>A high-throughput on-chip imaging platform that can rapidly monitor and characterize various cell types within a heterogeneous solution over a depth-of-field of ~4mm and a field-of-view of ~10 cm^2 is introduced. This powerful system can rapidly image/monitor multiple layers of cells, within a volume of ~4 mL all in parallel without the need for any lenses, microscope-objectives or any mechanical scanning.
<br> <br>
In this high-throughput lensless imaging scheme, the classical diffraction pattern (i.e., the shadow) of each micro-particle within the entire sample volume is detected in less than a second using an opto-electronic sensor chip. The acquired shadow image is then digitally processed using a custom developed &lsquo;&lsquo;decision algorithm&rsquo;&rsquo; to enable both the identification of the particle location in 3D and the characterization of each micro-particle type within the sample volume.
<br> <br>
Through experimental results, we show that different cell types (e.g., red blood cells, fibroblasts, etc.) or other micro-particles all exhibit uniquely different shadow patterns and therefore can be rapidly identified without any ambiguity using the developed decision algorithm, enabling high-throughput characterization of a heterogeneous solution.</p></div><p>

<tokenext>Here are some more details from the abstract of a relevent paper : A high-throughput on-chip imaging platform that can rapidly monitor and characterize various cell types within a heterogeneous solution over a depth-of-field of ~ 4mm and a field-of-view of ~ 10 cm ^ 2 is introduced .
This powerful system can rapidly image/monitor multiple layers of cells , within a volume of ~ 4 mL all in parallel without the need for any lenses , microscope-objectives or any mechanical scanning .
In this high-throughput lensless imaging scheme , the classical diffraction pattern ( i.e. , the shadow ) of each micro-particle within the entire sample volume is detected in less than a second using an opto-electronic sensor chip .
The acquired shadow image is then digitally processed using a custom developed       decision algorithm       to enable both the identification of the particle location in 3D and the characterization of each micro-particle type within the sample volume .
Through experimental results , we show that different cell types ( e.g. , red blood cells , fibroblasts , etc .
) or other micro-particles all exhibit uniquely different shadow patterns and therefore can be rapidly identified without any ambiguity using the developed decision algorithm , enabling high-throughput characterization of a heterogeneous solution .
