Which Technique Is Used In The Making Of Biochips Mcq?

21. Which technique is used in the making of biochips? A. Nanolithography.

Which of the following technology is used in making memory chips?

Memory chips consist primarily of silicon, which is obtained from sand. The process of making sand into silicon involves melting, cutting, polishing and grinding. The silicon is pressed and cut into integrated circuits.

What are the approaches used in nanofabrication Mcq?

Explanation: Colloidal dispersion is an example of bottom up approach in the synthesis of Nano particles. Attrition, milling and etching are typical top down methods.

Which of the following can be used as nanocarriers?

Commonly used nanocarriers include micelles, polymers, carbon-based materials, liposomes and other substances.

Which one the following techniques is used for the synthesis of 2 D nanostructures *?

Mechanical exfoliation is a straightforward method to obtain only one- or few-layer nanosheets, which well maintains the crystal structure and properties. Beside this, versatility and low cost of this method make it highly popular for synthesizing 2D materials and extremely convenient for fundamental research.

What materials are used to make chips?

Silicon is the material of choice in the chip industry. Unlike the metals normally used to conduct electrical currents, silicon is a ‘semiconductor’, meaning that its conductive properties can be increased by mixing it with other materials such as phosphorus or boron.

What is the function of the chip select lines in a memory chip Mcq?

Chip select (CS) or slave select (SS) is the name of a control line in digital electronics used to select one (or a set) of integrated circuits (commonly called “chips”) out of several connected to the same computer bus, usually utilizing the three-state logic.

Which of the following method is top-down method for nanomaterials Mcq?

Which of the following is an example of top-down approach for the preparation of nanomaterials? Explanation: Mechanical grinding is an example of top-down approach for the preparation of nanomaterials.

Which method is used to prepare nanoparticles?

The Polyol method is a chemical method for the synthesis of nanoparticles. This method uses nonaqueous liquid (polyol) as a solvent and reducing agent. The nonaqueous solvents that are used in this method have an advantage of minimizing surface oxidation and agglomeration.

Which of the following are methods used to measure microscopic sizes Mcq?

Clarification: Sieve analysis, microscopic examination and sedimentation analysis are the three methods of particle size measurement.

Which metal is used with nanoparticles for antibiotic delivery?

Although research has been expanded over the recent years to other less-common metals, the most widely used materials in metal-based nanoparticles include silver, gold, copper, iron, and zinc [17,18,19].

Which property of nanomaterials make them suitable to be used for elimination of pollutants?

have enhanced chemical activity
Which property of Nanomaterials make them suitable to be used for elimination of pollutants? Explanation: Nanomaterials have enhanced chemical activity. Due to this, they can be used as catalysts to react with toxic gases such as CO and NO₂ in automobile catalytic converters.

What are different nanocarriers we use for transport of medication to site?

Various nanocarriers such as liposomes, magnetic nanoparticles, polymeric nanoparticles, dendrimers, solid lipid nanoparticles, and magnetic liposomes are explored for targeted drug delivery to overcome multiple drug resistance.

Which of the following is an example of two-dimensional nanomaterials?

In recent years, 2D nanomaterials such as graphene, hexagonal boron nitride (hBN), and metal dichalcogenides (MX₂) have attracted a lot of attention due to their satisfactory properties and widespread uses in the electronics, optoelectronics, catalysts, energy storage facilities, sensors, solar cells, lithium batteries

Which is mechanical method of synthesis of nanomaterials?

1. Mechanical milling. Mechanical milling is a cost-effective method for producing materials at the nanoscale level from bulk materials. Mechanical milling is an effective method for producing blends of different phases, and it is helpful in the production of nanocomposites.

What are the two basic approaches for the synthesis of nanomaterials?

a) Top- down approach b) Bottom–up approach. Top-down approach involves the breaking down of the bulk material into nanosized structures or particles.

Where are chips made?

But today, 75 percent of production takes place in East Asia. Ninety percent of the most advanced chips are made in Taiwan. China is doing everything it can to take over the global market so they can try to outcompete the rest of us and have a lot of applications — including military applications.”

What are chips used for?

computer chip, also called chip, integrated circuit or small wafer of semiconductor material embedded with integrated circuitry. Chips comprise the processing and memory units of the modern digital computer (see microprocessor; RAM).

What mineral is used to make chips?

silicon
Computer chips are made of silicon, which is a semiconductor, andm in order to make the most efficient use of it, chip manufacturers use sand that contains as much silicon as possible. The mineral quartz is ideal for this purpose because its two main components are silicon and oxygen.
