Electrons, Molecules, and Safety: A New Screening Tool

February 6, 2025

Picture this: tiny, super-selective sensors scouring through food to keep us safe. These aren’t your everyday sensors; they’re molecularly imprinted electrochemical sensors (MIECSs), crafted from something called molecularly imprinted derivative materials (MIDPs). Think of them like lock and key sys

Detecting Copper Ions with Graphene: A Fluorometric and Visual Approach

November 21, 2024

Scientists have discovered a new way to detect copper ions (Cu²⁺) using tiny particles called graphene quantum dots (GQDs). Here's how it works: when copper ions and a chemical called ascorbate mix, they create a reaction that makes highly reactive hydroxyl radicals (·OH). These radicals can mess wi
