Sublingual delivery means delivering medicine under the tongue. This area is not a very common place to deliver drugs, but it is very effective for the drugs to be absorbed quickly into the body.
A Swiss biotech company, BioLingus, has developed sublingual delivery of peptides (肽) and proteins. It has opened the door to non-invasive delivery of many biological drugs that had so far only been taken through injections.
The primary challenge in developing the technique was stabilising the proteins. BioLingus turned to nature to find a solution. The seeds of plants contain a high concentration of proteins, which have to survive and remain complete for years, sometimes in extreme conditions of temperature, moisture, or drought. By mimicking these mechanisms, BioLingus has been able to come up with a way to preserve and stabilise proteins for a very long time at room temperature through advanced bioengineering.
And because of this, sublingual drugs are more adaptable than injection solutions that must usually be refrigerated. In itself, this opens up the possibility for social innovation as well as biological innovation.
Due to the strong stability of BioLingus' technology, sublingual drugs are very well suited for use in some less developed countries. Biological drugs usually have to be cooled all the way from manufacturing right up to when they reach the patient, and then injected. In many less developed countries, however, effective logistical cold chains are non-existent or not very good. With BioLingus' sublingual technology, however, the cold chain can be minimised or not needed at all.
In addition, because the drugs can be given orally instead of by injection, complications (并发症) due to infected needles are also prevented. What's more, although the technology is hi-tech, from a manufacturing perspective it is relatively low-cost. So, the combination of these factors makes it an excellent technology for use in some less developed countries—very much a social innovation.
1. Which of the following inspired BioLingus' solution to stabilising the proteins?
A. Proteins contained in plants.
B. Plants that live in extreme conditions.
C. The ways proteins survive extreme conditions.
D. Seeds growing at a steady and high temperature.
2. What does the underlined word “this” in Paragraph 4 refer to?
A. Proteins in injection solutions must be refrigerated.
B. BioLingus came up with a technology through biomimicry.
C. Sublingual drugs are both socially and biologically innovative.
D. Sublingual drugs keep proteins stable for a long time at room temperature.
3. Why is sublingual delivery suited to some less developed countries?
A. Because these countries lack effective cold chains.
B. Because it is easier to be accepted in these countries.
C. Because it is less expensive and more high-tech than injection solutions.
D. Because there are more complications due to infected needles in these countries.
