Design two PCBs based on a biological research paper

I would like to have two things designed that are based on the paper that you will find attached. 1) A "needle" array in a hexagonal pattern as described in the paper. The difference to the paper would be that the needles need to be a standard, gold coated, round contact pin of appropriate length. Ideally a cheap part available in large quantities. The needle array must be divided into 3 electrical subsets as described. The array must fit into one well of a multi-well cell culture plate. The dimensions are shown in the attached file. The array will be used in exactly the same manner as in the paper, to electroporate cells. The PCB would sit on top of the well of the plate and the gold pins sticking down into the liquid. The pins will need to get within 0.5 to 1 mm of the well bottom. 2) The electroporator will produce square wave pulses of up to 1000 V. The paper vaguely describes a circuit sitting between the +/- output of the electroporator and the needle array with 3 sets of pins to switch polarity from 1/2 to 1/3 to 2/3 and so forth. The needle array would be a disposable part that is used once and discarded. Production/population/soldering must be automatable.

Dear Valued Employer, My name is Martin and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for an electronics engineer capable of designing two custom PCBs based on a research paper. The file you have provided is a drawing of 24-well plate and a cover. There's no research paper as stated in the project description. However, I did a brief research on the topic of "electroporation device for gene transfer to cultured cells" and I found a couple of sources presenting solutions to the problem. Also, I stumbled across a couple of professional products for this specific task and purpose. A custom device for this specific task could probably be designed and developed, however some good scope and well documented requirements should be first discussed, documented and present. What's the reason to look for a non-standard readily available solution for a well known provider? Delivery term could be further negotiated once I start working on the project. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for you time. Kind Regards Martin K.

This seems like an interesting project. From the brief description I think it is unrealistic to offer to deliver it in seven days. If the project is intended to facilitate electroporation of specific cell types there is probably a broader application context that needs to be taken into consideration? Do you feel comfortable in providing a link to the paper that you reference? It seems that you may have only attached the electrode array design image? Interested and happy to assist, but would need more information to make an informed recommendation.
