Copper will change post-pandemic lifestyle

Copper and it’s alloy has antibacterial properties, hence an everyday tool made of these material will help in performing daily tasks without getting infected post corona pandemic.

Copper was also used to cure medical problems in ancient India is an important component of Ayurveda medicine today.

Hippocrates in Greece and the Aztecs used copper oxide and copper carbonate, combined with other chemicals such as sodium carbonate, olive paste and honey, to treat skin infections

Workers in Paris were protected from several cholera epidemics and French wineries even applied copper sulphate and slaked lime, called Bordeaux mixture, to vines to prevent fungal attack.


According to antimicrobial copper researcher Marisol Navarrete, “The ion of Cu interact with membrane of bacterial cell, there metabolism get disturbed and get killed by Cu.”

Positive ion of Cu attracts negative charge of bacteria membrane, those ions punches more hole in membrane letting more holes.

Various reactions Cu ions can generate high energy hydroxyl radicals, an oxygen bounded with hydrogen with unpaired electron.

Cu+ + H2O2 -> Cu2+ + OH- + OH+

Hydroxyl radicals reacts with and damage any biological molecule including DNA, proteins and carbohydrates.


The study of the antimicrobial properties of metallic copper surfaces is a relatively recent development and gained momentum when the Environmental Protection Agency (EPA) registered almost 300 different copper surfaces as antimicrobial.

Summarizes the species tested, test procedures, and killing kinetics. In general, microbes were inactivated on Cu within hours.

Bacteria, yeasts, and viruses are rapidly killed on metallic Cu surfaces, and the term “contact killing” has been coined for this process.

Contact killing of microbes by copper surfaces


2010’s study in Birmingham studying bacteria fighting properties of Cu and brass, they found 90-100% fewer bacteria on Cu and brass surfaces than on stainless steel even after 6 months.

Recently study by US National Health Institute scientists tested the covid19 viruses on plastic, stainless steel, copper, and cardboard. The result were corona virus remained active on plastic and stainless steel surfaces for two to three days under the conditions in this experiment. It remained infectious for up to 24 hours on cardboard and four hours on Cu.

While world is still fighting against corona virus, behavioral science and the broad sweep of history suggest that COVID-19 will transform our daily lives in the long run.

An ongoing University of Southern California study published its first round of results in March, reporting that the coronavirus had already created significant shifts in people’s behavior.

Among the top findings: 85 percent of people reported washing their hands or using sanitizer more often than before, and 61 percent reported following social distancing guidelines. 20 percent reported stockpiling essentials like food or water.


A little Cu won’t kill you. Cu clad surfaces in an intensive care unit are shown circled. Cu cladding was found to reduce HAI, or healthcare-associated infections by 58 percent in one study.

Use of  Copper in medical field

To avoid unnecessary touching also, Cu based antimicrobial everyday tool will be seen in huge number. These EDC tools can reduce the point-of-contact area and keep your hands clean. There are large number of kickstarter like CleanTouch and Hygeine Hand who already have such EDC tools.

Also places where EDC tool proposed can be used to do daily task like:

  • Press buttons
  • Touch ATM screens
  • Door handles
  • Self-checkout screens and keypads
  • Car park ticket machine buttons
  • Elevator buttons
