Mesoporous materials have pore sizes between 2-50 nm which gives them high surface areas of 400-1000 m2/g. Common types include MCM-41, MCM-48, MCM-50, HMS, and SBA-15. They can be synthesized using hard or soft templating methods. Applications include drug delivery, adsorption, chromatography, catalysis, sensors, and diagnostics due to their chemical stability, large pore volumes, and tunable surface properties.

17. Diagnostics
 Chemical stability.
 Low toxicity
 Flourescent markers
 Drugs can be used to track the location of
therapeutic agents and their activity.

18. ADSORBENT
 Use as adsorbents for various gases, liquids and toxic
heavy metals.
 Based upon surface property
hydrophobic, hydrophilic

19. CHROMATOGRAPHY
 Large pore volume surface area pore-size
distribution of mesoporous silica, make it a good
candidate for size exclusion chromatography.
 As stationary phases.

21. DRUG DELIVERY SYSTEMS
 Drug efficiency.
 Drug carrier must be non-toxic and inert during the
treatment period.
 Silica based Mesoporous materials have great
relevance for such life science applications.

22. CATALYSIS

23. SENSORS
 Have great potential in the field of gas sensing.
 Act as active layers in gas sensors based on various
operating principles, such as capacitive, resistive, or
optical sensing.
