How to check for a string against json encode array in a table in Laravel?

I am having an issue with a Laravel project. I have a few checkbox of computer specification which I want to check against the database field that I am having called tech_specs. This tech_specs field contains the serialize array of all the tech_specs that are available for that specific product. I just want to list out the products having that particular specification. Please let me know how to proceed.

Controller Function

public function GetPage(Request $request,$page_slug){
