Using Facemasks for Detection of Covid-19

 

Using Facemasks  for Detection  of  Covid-19

 

Can a facemask be used as a  Biosensor ?  How it would be  if  a facemask, 

after being used  for   some time would be able to detect Covid-19 virus ?  

Very interesting,  isn’t  it ?  Rest assured,  now it is a reality,  thanks to the 

recent research by Dr. Peter Nguyen &  Dr. Luis R. Soenksen  at  the 

MIT/Harvard Laboratory where,  as interviewed  by  Mrs. Emily Henderson, 

they had been trying to bring advanced biological circuits  outside  the  

laboratory in a miniature form,  to develop   a wearable  like a facemask

which would contain biosensors for detection of  Covid-19 ;

 

Biosensors

To identify various physiological signals of a human body we use various 

kinds of sensors like pulse oxi-meter,  pressure machine, recently innovated 

Apple watch etc.

However, in contrast to such various electronic, mechanical or optical 

sensors, biosensors  use specially engineered genetic circuits to create  a 

sensor  & detector for a desired molecular target through biology ;  It was 

observed that biosensors are especially  suited  for pathogen & toxin 

detection, as they are  most able  to directly interact  with these molecular 

components to give the desired results ; 

 

Research  summary  in very simple  words

During the research,   biosensors  were  attached to standard K95 facemask to 

help in the  detection of  the virus which,  as the researchers said,  took little 

time to give the  desired  results ;  The sensors could be activated  by pressing 

a button  & the results were reflected with a readout strip in a span of ninety 

minutes ;  The accuracy of the test  was the same as that of  a standard  

Rt-PCR test which  is conducted to detect Covid-19 ;

As per Mr. N. Guyen, the co-author of the study, they  had brought a whole 

laboratory into  a  small  sensor that would work with any mask ;  He also 

added  that the technology  has brought together the accuracy of the PCR test 

which is  accepted  globally  as the  standard test for detecting  Covid -19 ;

 

Benefits

It is very convenient -  As we normally wear a facemask  for a considerable

period of  time,  why not perform a test while we are wearing the same ?

 

 It is inexpensive – As per report, the prototype Covid-19 diagnostic costs 

 USD 5.00,  excluding the cost of the mask itself ;  Just think, at this cost 

you get  an all- in-one disposable facemask while performing the  Covid -19 

detection test  which is as accurate as a standard  Rt-PCR test ; However, 

along with the mass  production this cost is likely to decrease ;

 

 It is non-invasive – It is able to detect the virus from the user’s breadth  only ;

 The longer the breadth capture, the more sample will be available for the

 biological analysis ;

 

 No instrumentation & minimal user operation -  The sensor is fully integrated

  into the material, and  the user needs only to  press a button  to activate the

  detection test ;  There are no instruments or power needed ;

 

  It runs at room temperature -  Though it sounds simple but was hard to

  achieve ; However, all the reactions are able to work at room temperature, 

  thus  dispensing  with any heating process etc., as required in a  Rt-PCR test ;

Black Fungus - A General Awareness

  Black Fungus   Slowly following   the Covid-19 Pandemic   a    rare,    deadly & aggressive fungal   infection is spreading as epidemic in India ; As per   recent BBC news already nearly 9 thousand cases have been detected   in various states   like Gujarat, Rajasthan, Tamil Nadu, Orissa and Telengana etc.   How Caused   - Black Fungus or Mucormycosis is caused by a group of fungi that normally live in the environment, particularly   as moulds found in   soil and in decaying organic matters such as leaves, compost piles or rotten wood (CDC- 13/05/2021) ; People get Mucormycosis  of which there are several types by breathing in the fungal spores ; It may also come in hospitals and homes from  air humidifiers or oxygen tanks containing dirty water ; Line of Treatment According to Centre for Disease Control (CDC), the infection needs to be caught early as it is aggressive & dead tissues have to be scraped away ;   Unfortunately, surgeons   sometimes   have to remove 

Covid 19 - The DANGER of a Two Speed Response

  Covid-19 – The DANGER  of   a Two Speed Response   A Global Battlefield The human civilization is just in the middle of a battle now, the battle against a tiny virus   called   Coronavirus ;   To survive, our civilization has to   fight unitedly   to win over this enemy   where   the battlefield remains to be the   whole   area of our planet ; The UN Secretary General Mr. Antonio Guterres   on   24 th   May,   2021, has urged the countries to take bold   decisions now to both end the crisis and   build a safe & healthy future for all ;     The Grim Picture As per a recent report of the WHO Chief,   Mr. T.A. Ghebreyesus, there have been more Covid-19   cases   so far this year than in the whole of   the previous year (2020),   “On current trends” said he, “ the number of deaths will overtake last year’s total within the next three weeks” ;   As against this scenario, most of the   vaccine doses or 75 % ,   have been   administered   only in just   10

Pandemic's Effect on Family Relationship

  Pandemic’s Effect on Family Relationship   It will be a very interesting   discussion if we look into the matter   of   some sort of changes   in family   relationship in this global pandemic atmosphere ;   This Covid-19 Pandemic, being   an once-in-a-century affair, followed by a series  of Lock-downs in almost  every  country,  has so far affected in every  sphere  of  human life, namely, social, cultural,  economic  & also in   family-lives in  almost all the  corners of our planet ;   However,   to   limit the   volume   of this   writing ,   let us   confine our   brief  discussion only  to the  changes  that might have been noticed   due to this pandemic situation  within the family  circles  of two  different  economic  sectors,  i.e., the Working Class &/or Lower- Middle Class People   and   the   Upper-Middle Class people ; At the beginning it should be made clear that the points narrated  below  are not at all comprehensive,  written on the basis of only
